Lithium-ion and lithium-polymer batteries

Engineering thought is constantly evolving: it is stimulated by constantly emerging problems that require the development of new technologies to be solved. At one time, nickel-cadmium (NiCd) batteries were replaced by nickel-metal hydride (NiMH), and now lithium-ion (Li-ion) batteries are trying to take the place of lithium-ion (Li-ion) batteries. NiMH batteries have to some extent supplanted NiCd, but due to such undeniable advantages of the latter as the ability to deliver high current, low cost and long term services were unable to provide their full replacement. But what about lithium batteries? What are their features and how do Li-pol batteries differ from Li-ion? Let's try to understand this issue.

As a rule, when buying a mobile phone or laptop computer, we all don’t think about what kind of battery is inside and how these devices differ in general. And only then, having encountered in practice the consumer qualities of certain batteries, do we begin to analyze and choose. For those who are in a hurry and want to immediately get an answer to the question of which battery is optimal for a cell phone, I will answer briefly - Li-ion. The following information is intended for the curious.

First, a short excursion into history.

The first experiments on creating lithium batteries began in 1912, but it was only six decades later, in the early 70s, that they were first introduced into household devices. Moreover, let me emphasize, these were just batteries. Subsequent attempts to develop lithium batteries(rechargeable batteries) have failed due to safety concerns. Lithium, the lightest of all metals, has the greatest electrochemical potential and provides the greatest energy density. Batteries using lithium metal electrodes offer both high voltage and excellent capacity. But as a result of numerous studies in the 80s, it was found that cyclic operation (charge - discharge) of lithium batteries leads to changes in the lithium electrode, as a result of which thermal stability decreases and there is a threat of the thermal state getting out of control. When this happens, the temperature of the element quickly approaches the melting point of lithium - and a violent reaction begins, igniting the gases released. So, for example, large number lithium mobile phone batteries supplied to Japan in 1991 were recalled after several fire incidents.

Because of lithium's inherent instability, researchers have turned their attention to non-metallic lithium batteries based on lithium ions. Having lost a little in energy density and taking some precautions when charging and discharging, they received safer so-called Li-ion batteries.

The energy density of Li-ion batteries is usually twice that of standard NiCd, and in the future, thanks to the use of new active materials, it is expected to increase it even further and achieve three times superiority over NiCd. In addition to the large capacity, Li-ion batteries behave similarly to NiCds when discharged (their discharge characteristics are similar in shape and differ only in voltage).

Today there are many varieties of Li-ion batteries, and you can talk for a long time about the advantages and disadvantages of one type or another, but you can distinguish them by appearance impossible. Therefore, we will note only those advantages and disadvantages that are characteristic of all types of these devices, and consider the reasons that led to the birth of lithium-polymer batteries.

Main advantages.

• High energy density and, as a consequence, large capacity with the same dimensions compared to nickel-based batteries.
• Low self-discharge.
• High voltage single cell (3.6 V versus 1.2 V for NiCd and NiMH), which simplifies the design - often the battery consists of only one cell. Many manufacturers today use just such a single-cell battery in cell phones (remember Nokia). However, to provide the same power, a higher current must be supplied. And this requires ensuring low internal resistance element.
• Low maintenance (operating) costs result from the absence of memory effect, requiring periodic discharge cycles to restore capacity.

Flaws.

Li-ion battery manufacturing technology is constantly improving. It is updated approximately every six months, and it is difficult to understand how new batteries “behave” after long-term storage.

In a word, a Li-ion battery would be good for everyone, if not for the problems with ensuring the safety of its operation and high cost. Attempts to solve these problems led to the emergence of lithium-polymer (Li-pol or Li-polymer) batteries.

Their main difference from Li-ion is reflected in the name and lies in the type of electrolyte used. Initially, in the 70s, a dry solid polymer electrolyte was used, similar to plastic film and non-conductive. electric current, but allowing the exchange of ions (electrically charged atoms or groups of atoms). The polymer electrolyte effectively replaces the traditional porous separator impregnated with electrolyte.

This design simplifies the production process, is safer and allows the production of thin batteries free form. In addition, the absence of liquid or gel electrolyte eliminates the possibility of ignition. The thickness of the element is about one millimeter, so equipment developers are free to choose the shape, shape and size, even including its implementation in fragments of clothing.

But so far, unfortunately, dry Li-polymer batteries have insufficient electrical conductivity at room temperature. Their internal resistance is too high and cannot provide the amount of current required for modern communications and power supplies. hard drives laptop computers. At the same time, when heated to 60 °C or more, the electrical conductivity of Li-polymer increases to an acceptable level, but this is not suitable for mass use.

Researchers are continuing to develop Li-polymer batteries with a dry solid electrolyte that operates at room temperature. Such batteries are expected to become commercially available by 2005. They will be stable, allow 1000 full cycles charge-discharge and have a higher energy density than today's Li-ion batteries

Meanwhile, some types of Li-polymer batteries are now used as backup power supplies in hot climates. For example, some manufacturers specifically install heating elements that maintain a favorable temperature for the battery.

You may ask: how can this be? Li-polymer batteries are widely sold on the market, manufacturers equip phones and computers with them, but here we are saying that they are not yet ready for commercial use. It's very simple. IN in this case We are not talking about batteries with dry solid electrolyte. In order to increase the electrical conductivity of small Li-polymer batteries, a certain amount of gel-like electrolyte is added to them. And most Li-polymer batteries used for cell phones today are actually hybrids because they contain a gel-like electrolyte. It would be more correct to call them lithium-ion polymer. But most manufacturers simply label them as Li-polymer for advertising purposes. Let us dwell in more detail on this type of lithium-polymer batteries, since at the moment They are the ones that are of greatest interest.

So, what is the difference between Li-ion and Li-polymer batteries with gel electrolyte added? Although the characteristics and efficiency of both systems are largely similar, the uniqueness of the Li-ion polymer (you can call it that) battery is that it still uses a solid electrolyte, replacing a porous separator. Gel electrolyte is added only to increase ionic conductivity.

Technical difficulties and delays in ramping up production have delayed the introduction of Li-ion polymer batteries. This is caused, according to some experts, by the desire of investors who have invested a lot of money in the development and mass production of Li-ion batteries to get their investments back. Therefore, they are in no hurry to switch to new technologies, although with mass production of Li-ion polymer batteries will be cheaper than lithium-ion ones.

And now about the features operation of Li-ion and Li-polymer batteries.

Their main characteristics are very similar. The charging of Li-ion batteries is described in sufficient detail in the article. In addition, I will only give a graph (Fig. 1) from, illustrating the stages of charge, and small explanations to it.

The charging time for all Li-ion batteries with an initial charging current of 1C (numerically equal to the nominal value of the battery capacity) averages 3 hours. Full charge is achieved when the battery voltage is equal to the upper threshold and when the charging current is reduced to a level approximately equal to 3% of the initial value. The battery remains cold during charging. As can be seen from the graph, the charging process consists of two stages. In the first (a little over an hour), the voltage increases at an almost constant initial charge current of 1C until the upper voltage threshold is first reached. At this point, the battery is charged to approximately 70% of its capacity. At the beginning of the second stage, the voltage remains almost constant and the current decreases until it reaches the above 3%. After this, the charge stops completely.

If you need to keep the battery charged all the time, it is recommended to recharge after 500 hours, or 20 days. Usually it is carried out when the voltage at the battery terminals decreases to 4.05 V and stops when it reaches 4.2 V

A few words about the temperature range during charging. Most types of Li-ion batteries can be charged with a current of 1C at temperatures from 5 to 45 °C. At temperatures from 0 to 5 °C, it is recommended to charge with a current of 0.1 C. Charging at sub-zero temperatures is prohibited. The optimal temperature for charging is 15 to 25 °C.

The charging processes in Li-polymer batteries are almost identical to those described above, so the consumer has absolutely no need to know which of the two types of batteries he has in his hands. And all those chargers, which he used for Li-ion batteries, are suitable for Li-polymer.

And now about the discharge conditions. Typically, Li-ion batteries discharge to a value of 3.0 V per cell, although for some varieties the lower threshold is 2.5 V. Manufacturers of battery-powered equipment typically design devices with a shutdown threshold of 3.0 V (for all occasions). What does this mean? The voltage on the battery gradually decreases when the phone is turned on, and as soon as it reaches 3.0 V, the device will warn you and turn off. However, this does not mean that it has stopped consuming energy from the battery. Energy, albeit small, is required to detect when the phone's power key is pressed and some other functions. In addition, energy is consumed by its own internal control and protection circuit, and self-discharge, although small, is still typical even for lithium-based batteries. As a result, if lithium batteries are left for a long period of time without recharging, the voltage on them will drop below 2.5 V, which is very bad. In this case, it is possible to disable internal circuit control and protection, and not all chargers will be able to charge such batteries. In addition, deep discharge negatively affects the internal structure of the battery itself. A completely discharged battery must be charged at the first stage with a current of only 0.1C. In short, batteries like to be in a charged state rather than in a discharged state.

A few words about temperature conditions during discharge (read during operation).

In general, Li-ion batteries perform best at room temperature. Operating in warmer conditions will seriously reduce their lifespan. Although, for example, a lead-acid battery has the highest capacity at temperatures above 30 °C, long-term operation in such conditions shortens the life of the battery. In the same way, Li-ion works better when high temperature, which initially counteracts the increase in internal battery resistance resulting from aging. But the increased energy output is short-lived, since rising temperatures in turn promote accelerated aging, accompanied by a further increase in internal resistance.

The only exceptions at the moment are lithium-polymer batteries with dry solid polymer electrolyte. They require a vital temperature of 60 °C to 100 °C. And such batteries have found their niche in the market for backup sources in hot climates. They are placed in a thermally insulated housing with built-in heating elements powered from an external network. Li-ion polymer batteries as backup batteries are considered to be superior in capacity and durability to VRLA batteries, especially in field conditions when temperature control is not possible. But their high price remains a limiting factor.

At low temperatures The efficiency of batteries of all electrochemical systems drops sharply. While NiMH, SLA and Li-ion batteries stop functioning at -20°C, NiCd batteries continue to function down to -40°C. Let me just note that again we are talking only about batteries of wide use.

It is important to remember that although a battery can operate in low temperatures, this does not mean that it can also be charged in these conditions. The charge susceptibility of most batteries at very low temperatures is extremely limited, and the charge current in these cases should be reduced to 0.1C.

In conclusion, I would like to note that you can ask questions and discuss problems related to Li-ion, Li-polymer, as well as other types of batteries, on the forum in the accessories subforum.

The most common types of batteries are lithium polymer and lithium ion. What are their features?

Facts about lithium polymer batteries

IN lithium polymer batteries a solid polymer electrolyte is used. In the very first samples of batteries of this type, created in the 70s, it was present mainly in a dry modification. This electrolyte did not actually conduct electric current, but it could exchange ions formed by lithium compounds. IN modern devices- laptops, mobile phones, gadgets - batteries are used, which also contain a certain amount of electrolyte in the form of a gel.

Lithium polymer batteries are capable of providing high level electricity density based on its size and weight. They are characterized by a fairly low self-discharge, do not have the so-called memory effect - when a charged battery during use is sometimes discharged only to a level that corresponds to the moment the battery is charged (that is, not necessarily to zero), and can also operate over a wide range of temperatures.

However, lithium polymer batteries are not always safe - especially if they overheat or become too hot. long charging. Batteries of the type under consideration have about 800-900 operating cycles, at which the level of capacity loss does not exceed 20%. The battery loses the same 20% of performance after 2 years of operation, even if it is not used but is in storage.

Lithium-polymer batteries are often very small in size - it is theoretically possible to produce batteries with a thickness of about a millimeter. The use of a metal body in their design is optional.

Facts about lithium-ion batteries

Design lithium ion battery consists of electrodes and separators, usually impregnated with liquid electrolyte. The first are represented by aluminum cathodes and copper anodes. Electric charge in batteries of this type is carried by a positively charged lithium ion, which has the ability to integrate into the crystal lattices of other substances and thus form new compounds. The cathodes in modern lithium-ion batteries are usually represented by compounds of lithium with cobalt, nickel, manganese, and iron phosphate.

Batteries of this type are characterized, like lithium-polymer products, by low self-discharge, but slightly exceed them in energy intensity. Lithium-ion batteries do not need to be charged and discharged periodically to maintain functionality.

Older models of lithium-ion batteries are considered unsafe to use, but those that include elements made from a lithium iron phosphate compound are considered quite reliable. Like lithium polymer devices, these types of batteries lose capacity over time - even when not in use.

Comparison

The main difference between a lithium-polymer battery and a lithium-ion battery is the use of a predominantly dry electrolyte (with a small percentage of gel) in the structure of the former, while the latter, as a rule, uses a liquid electrolyte. This predetermines the possibility, first of all, not to use a metal shell in the design of lithium-polymer batteries and to produce a battery of small size and thickness. In lithium-ion batteries, in turn, it is necessary - otherwise the electrolyte will leak out. The importance of using a metal shell can make it difficult for manufacturers to reduce the size of their batteries.

Having determined what the difference is between a lithium-polymer and a lithium-ion battery, we will reflect the conclusions in a small table.

Table

Lithium polymer batteries	Lithium-ion batteries
What do they have in common?
Have general principles transfer of electric charge - using lithium compounds
Characterized by low self-discharge
No memory effect
There is a common disadvantage in the form of capacity reduction over time
What is the difference between them?

Does not require a metal shell and can be small in size	Requires a metal shell, which determines their larger size compared to lithium-polymer batteries
Have slightly lower energy consumption	Have slightly higher energy consumption

Lithium- polymer battery is an improved version of the traditional lithium-ion battery. Its main difference is the use of a special polymer material, in which gel-like lithium-conducting inclusions are used as filling. This type of battery is used in many models of mobile devices, phones, digital devices, radio controlled cars and so on.

A traditional lithium polymer battery for household use cannot supply too much current. However, today there are special power varieties of such devices that can deliver a current that is many times greater than its capacity in ampere-hours.

Lithium polymer battery design

The difference between lithium polymer and lithium ion energy storage is the type of electrolyte used. IN polymer batteries a special polymer with a lithium-containing solution is used, and in ionic ones a regular gel electrolyte is used. In the power systems of the majority modern models A lithium polymer battery is used. This is due to the fact that it provides more powerful discharge currents. However, too strict separation There is no difference between these types of batteries, since they differ only in the nature of the electrolyte. This applies to charging and discharging features, operating rules and safety precautions.

Main Features

A modern lithium-polymer battery with the same mass is significantly more energy-intensive than nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries. They have a number of operating cycles of approximately 500-600. Let us recall that for NiCd it is 1000 cycles, and for NiMH it is about 500. Like lithium-ion, polymer carriers also age over time. Therefore, after 2 years, such a battery will lose up to 20% of its capacity.

Types of power lithium polymer batteries

Today there are two main types of such batteries - standard and fast-discharge. They differ in the level of maximum discharge current. This indicator is indicated either in units of battery capacity or in amperes. In most cases maximum level discharge current does not exceed 3C. However, some models can produce a current of 5C. In fast-discharge devices, a discharge current of up to 8-10C is allowed. However for household appliances fast-discharge models are not used.

Features of application

The use of a lithium-polymer battery can significantly increase the operating time of the electric motor while reducing the weight of the battery itself. Therefore, if you replace the usual NiMH battery 650 mAh for two ordinary lithium-polymer batteries, you can get 3 times more capacious energy carrier. Moreover, such a battery will be more than 10 g lighter. If you take fast-discharging batteries, then you can achieve even higher performance. Such a system will excellent option not only for small models of airplanes or helicopters, but also for impressive radio-controlled devices.

Lithium polymer batteries, unlike lithium-ion batteries, have performed well in small helicopters such as the Hummingbird and Piccolo. Similar models with conventional commutator motors can fly on two polymer batteries for half an hour. When using a brushless motor, this time increases to 50 minutes. This type batteries considered an ideal option for light-weight indoor aircraft. Their efficiency in this case is determined by their much lighter weight compared to NiCd batteries.

The only area in which the lithium-polymer battery is inferior to NiCd is the use in devices with ultra-high discharge current up to 50 C. However, it is quite possible that in a few years more powerful batteries this type. At the same time, prices for lithium polymer, lithium ion and NiCd batteries are approximately the same for the same mass of devices.

Features of operation

The operating rules for lithium-polymer and lithium-ion batteries are largely similar. When using a polymer battery, you must avoid certain dangerous situations that can cause irreparable harm to it:

• charging the device with a voltage of 4.2 volts per jar;
• discharge with currents with a load capacity exceeding the proper one;
• discharge with a voltage below 3 volts per cell;
• battery depressurization;
• heating the device above 60 degrees;
• long-term storage in a completely discharged state.

Lithium polymer and lithium ion batteries are characterized by a fire hazard during overheating and overdischarge. To combat this phenomenon, everyone modern batteries equipped with built-in electronic system, which prevents overdischarge or overheating. This is why a lithium polymer battery requires special charging algorithms.

Charger

The process of charging lithium polymer batteries is practically no different from charging lithium ion batteries. Charging of most lithium-polymer batteries with a starting charging current of 1C is achieved in approximately 3 hours. To achieve a full charge, it is necessary to have the battery voltage corresponding to the upper threshold. Besides, a necessary condition is to reduce the charge current to 3% of the nominal value. Moreover, during such charging, such a battery always remains cold. If you want to keep the battery constantly charged, then it is advisable to recharge approximately once every 500 hours, which corresponds to 20 days. As a rule, charging is usually carried out when the voltage at the battery terminals drops to 4.05V. Charging is stopped after the voltage at the terminals reaches 4.2V.

Charge temperature

Most lithium-polymer batteries can be charged at a temperature of 5-45 degrees at a current of 1C. If the temperature is in the range from 0 to 5 degrees, then it is recommended to switch to a current of 0.1C. Charging at sub-zero temperatures is completely prohibited in this case. Traditionally, it is believed that the most favorable conditions for charging are 15-25 degrees. Since all charging processes in lithium-polymer and lithium-ion batteries are almost identical, the same chargers can be used for them.

Discharge conditions

Traditionally, this type of battery discharges at a voltage of 3.0V per battery. However, some types of devices must be discharged at a minimum threshold of 2.5V. Manufacturers of mobile devices provide a shutdown threshold of 3.0V, which will be suitable for any type of battery. That is, as the battery discharges while the mobile device the voltage gradually drops and, when it reaches 3.0V, the device automatically warns you and turns off. However, the device still continues to consume some energy from the battery. This is required to detect when the power button is pressed or for other similar functions. Also, the energy here can be used for its own protection and control circuit. Moreover, a low level of self-discharge still remains characteristic of lithium-polymer carriers. Therefore, if you leave such batteries on long time, then the voltage in them may drop below 2.5V, which is very harmful. All internal protection and control systems may be disabled. As a result, such batteries can no longer be charged with conventional chargers. In addition, complete discharge is very harmful to internal structure batteries. Therefore, a completely discharged battery must be charged at the first stage with a minimum current of 0.1C.

Temperature during discharge

The lithium polymer battery performs best at room temperature. If you use your device in hotter environments, battery life may be significantly reduced. As for the lithium-ion battery, this battery works best at high temperatures. It initially prevents the internal resistance of the battery from increasing, which is thought to be a result of aging. However, subsequently the energy output is reduced and an increase in temperature accelerates the aging process due to an increase in internal resistance.

The lithium polymer battery has slightly different operating conditions, since it has a dry and solid electrolyte. The ideal temperature for its operation is 60-100 degrees. Therefore, such an energy carrier has become an ideal option for backup power sources in regions with hot climates. They are specially placed in a heat-insulating housing with built-in heating elements powered from an external network.

• The lithium polymer battery has superior capacity and durability to the lithium-ion battery.
• Ease of use in field conditions when there is no way to control the temperature.
• High energy density per unit weight and volume.
• Low self-discharge.
• Thin elements no more than 1 mm.
• Flexibility of form.
• No memory effect.
• Wide range operating temperatures from −20 to +40 °C.
• Insignificant voltage drop during discharge.

Disadvantages of lithium polymer batteries:

• Low efficiency at temperatures of -20 degrees and below.
• High price.

Technical progress is a machine that rolls without stopping! The fuel for this machine is more and more new problems of our modern world. Remember, not so long ago nickel-cadmium (NiCd) batteries were in use, they were replaced by nickel-metal hydride (NiMH). But today lithium-ion (Li-ion) batteries are trying to take the place of lithium-polymer (Li-pol) batteries. What is the difference between Li-pol and Li-ion? What are the advantages of lithium polymer over lithium ion batteries? Let's try to figure it out.

When we buy a phone or tablet, few people ask themselves the question: what kind of battery is inside? Only later, when faced with the problem of quickly discharging the gadget, do we begin to take a more detailed look at the “inside” of our device.

ABOUT lithium batteries became known in 1912, then the first experiments began, but they were not widely used. And only in the 70s, six decades later, these charging elements took their place in almost all household devices. Let us emphasize that for now we are talking only about batteries, not rechargeable batteries.

Lithium is the lightest metal, it also provides the highest energy density and has significant electrochemical potential. Batteries that are based on lithium metal electrodes have large capacity and high voltage. In the 80s, as a result of numerous studies, it turned out that the cyclic operation of lithium batteries (charge/discharge process) leads to the ignition of chargers, and after them, the gadgets themselves. So, in 1991, several thousand phones were recalled in Japan due to a fire hazard. Because of these dangerous properties lithium, scientists have turned their attention to non-metallic lithium batteries based on lithium ions. And after some time, a safer version of the charger was created, which was called lithium-ion (Li-ion).

Today, the lithium-ion battery is found in almost all mobile devices, it has a large number of varieties, has a lot of positive qualities, but also disadvantages, which we will talk about in more detail.

Advantages of lithium-ion batteries:

High energy density and, as a result, high capacity

Low self-discharge

High voltage of a single element. This simplifies the design - often the battery consists of only one element. Many manufacturers today use cell phones just such a single-cell battery (remember Nokia)

Low cost of maintenance (operating costs)

No memory effect requiring periodic discharge cycles to restore capacity.

Flaws:

The battery requires a built-in protection circuit (which further increases its cost) that limits the maximum voltage across each battery cell during charging and prevents the cell voltage from dropping too low when discharging

The battery is subject to aging, even if not used and just sitting on a shelf. The aging process is typical for most Li-ion batteries. For obvious reasons, manufacturers are silent about this problem. A slight decrease in capacity becomes noticeable after just a year, regardless of whether the battery has been in use or not. After two or three years it often becomes unusable

Higher cost compared to NiCd batteries.

Lithium-ion batteries are constantly being improved, technology is improving. And this battery would be good for everyone if it were not for the safety problems when using it and the high price. All these reasons became the basis for the creation lithium polymer batteries (Li-pol or Li-polymer). The most obvious and most basic difference between Li-pol and Li-ion is the type of electrolyte used. The use of solid polymer electrolyte significantly reduces the cost of creating a battery and makes it safer, and also allows you to create thinner chargers. Why hasn't the lithium-polymer battery completely replaced its predecessor? One of the possible versions expressed by experts is that investors who have invested large sums in the development and mass implementation of Li-ion batteries are trying to return the investment.

Let's summarize. Generally speaking, a lithium polymer battery is a more advanced version of a lithium-ion battery. Judge for yourself:

Advantages of Li-pol and Li-ion batteries

To summarize, we can say that, thanks to modern technologies, we have two types of reliable external batteries. With development mobile technologies, with the advent of smartphones, tablets and many others digital gadgets, with the creation of energy-intensive applications, users are faced with the problem of “dead battery”. Of course, both Li-ion and Li-Pol batteries immediately found their application in external chargers.

This is an excellent solution for modern life. The most important thing when choosing a powerbank is not to run into scammers (we wrote more about how to distinguish a fake from an original , but about how to use a store’s website to understand with 100% certainty that they will sell you a fake -
