Lithium-ion battery life and how to improve it

Lifetime of Lithium Ion Battery Each charge and discharge process of a lithium ion battery is called a charge cycle. From the beginning of operation, the capacity of a lithium-ion battery will drop slightly after each cycle, which is determined by the nature of the battery's electrode material. According to national standards, when the capacity drops to 60% of the rated capacity, the battery life is considered to be over. Generally, the life of a lithium-ion battery is not less than 500 cycles, which means that after 500 charging cycles, the capacity is not less than 60% of the rated capacity. The method to improve the life of lithium-ion batteries is to charge and discharge the battery. This puts a relatively large load on the electrode material. Do not fully charge each time, and do not completely empty the discharge, which can greatly extend the life. Generally speaking, 5 to 10 shallow discharge cycles are equal to 1 full discharge cycle. In addition, reducing the charging voltage can also extend battery life. In fact, don't take the battery too delicately. The natural attenuation of a lithium-ion battery is still very obvious. A new battery will be stored for a long time, but the capacity will decrease the same. If stored fully charged, the drop will be even worse. Some tests say that if the charge and discharge process is controlled at 80% of the capacity, the cycle life can exceed 2000 times. Therefore, you don’t have to charge the battery every time you run out, and don’t have to charge it to 100%. In addition, when you plug in the computer to upload files, the USB port charging function does not need to be turned off, and the charging for that little time will not affect the cycle life, because it will not reach a cycle at all.
