What is the general lifespan of lithium batteries?

The lifespan of lithium batteries is typically 3 to 5 years.

At present, there are two main types of lithium batteries used in electric vehicles, namely ternary lithium batteries and lithium iron phosphate batteries. The first has a relatively high cell voltage of 3.7 volts and. the latter The voltage is lower, the voltage is 3.2 volts.

The advantages of ternary lithium batteries are high cell voltage, light weight, high energy density and less influence on temperature. However, the disadvantage is that the number of charging times is relatively small, only about 800 times. . It is very easy to catch fire when damaged by external force and leakage. Battery life is typically 3-5 years. Lithium iron phosphate batteries can theoretically be charged up to 2000 fois and have a relatively long lifespan. However, this type of battery has a fatal disadvantage, which is that it is greatly affected by temperature.

Precautions for using lithium batteries

Theoretically, the life of lithium batteries can reach about 500 times after full discharge, but As long as we use them mobile phones, we must Charging will damage the battery. Although the degree of this damage is very small, it is also very objective when accumulated, the battery life can be significantly shortened.

The optimal temperature for storing lithium batteries is 20°C, which can vary somewhat. Generally, air humidity does not exceed 50%. As long as it is not completely exposed to air or water vapor, it will practically not damage the battery life.

However, batteries in bedhium still have certain storage temperature requirements. Specially treated lithium batteries can work in a low temperature environment of -60°C, but ordinary lithium batteries can only work at around -20°C. . , once the temperature is lower than this value, battery power consumption accelerates.
