lithium polymer battery

　　What is the service life of ternary lithium polymer battery?

　　With the current technical strength of ternary lithium polymer battery, if used properly, battery vehicles can be used for at least 5 years. If operated incorrectly, it will cause a lithium battery life degradation coefficient of 2-3 years.

　　If it is used appropriately, it mainly depends on whether it can comply with the shallow charging and shallow discharge standards, and it cannot be used indiscriminately.

　　The service life of power engineering lithium polymer battery reaches 2,000 cycles. The intelligent battery management system can limit "overcharging and power loss". How long is the current service life of lithium polymer battery? There are many factors that affect the service life of power lithium polymer battery, including not only the characteristics of the system itself, but also its processing process, application conditions, etc. The high-quality battery system, coupled with the scientific management information system, can achieve a long service life.

　　Detailed introduction to the advantages and disadvantages of ternary lithium polymer battery.

　　Advantages of lithium polymer battery:

　　High specific energy, reaching over 200WH/Kg;

　　The high-voltage service platform is high. The potential difference platform is an important indicator of the specific energy of the battery. It determines the basic efficiency and cost of the battery. Therefore, the selection of materials is very important. The higher the voltage, the greater the specific volume. There is no doubt that with the same volume, weight, and even rechargeable batteries, the voltage will have a longer life than ternary material lithium polymer battery.

　　Disadvantages of lithium polymer battery:

　　High productivity but low efficiency

　　Model3 uses NCR18650A rechargeable battery with a capacity of 3070MAH. The continuous charging and discharging current can only reach 2C, and the actual charging and discharging effect of 2C is the best.

　　The capacitor has a fast attenuation coefficient and a short period.

　　Under the same battery charging current, each cycle frequency of Tesla electric vehicle's battery is from 0% to 100%. After that, the battery power will attenuate to 55%. Even if it is cycled 3000 times, the system volume can still maintain 70%. % capacity, if the battery cycle frequency is reduced from 0%-50% to 55%.

　　Not safe.

　　No matter which brand of ternary material lithium battery it is, fire will occur if there is an internal short circuit or the positive electrode of the battery is exposed to water. Even if the 18650 battery is protected by an aluminum shell, it still cannot withstand extreme impacts.

　　Positive ion toxic side effects (the temperature of ternary lithium polymer battery rises significantly after charging a high-power battery, and it is very easy to release CO2 and ignite after high temperature).

　　Compared with lithium iron phosphate rechargeable batteries, the biggest feature of ternary lithium polymer battery is that the company consumes a lot of power. However, a very big drawback of ternary lithium polymer battery is that they are highly resistant to impact and have low open flames at high temperatures. Therefore, the maintenance requirements for ternary lithium polymer battery are very high, just in case.
