Battery Manufactory

In today's era of rapid technological development, lithium batteries , as the "heart" of various electronic devices, have been deeply integrated into our daily lives. Whether it is a mobile phone, a laptop, or an electric car, it is inseparable from the support of lithium batteries. However, everyone must have had such doubts: How long can lithium batteries last? Today, let's discuss this issue in depth. 1. Types and life basis of lithium batteries There are many members in the lithium battery family, and the common ones are lithium cobalt oxide , lithium iron phosphate, and ternary lithium batteries. Different types of lithium batteries have certain differences in their theoretical lifespan. For example, although lithium cobalt oxide batteries have a high energy density and can make electronic devices have good battery life, their cycle life is relatively short, generally around 500-1000 times. The cycle life here refers to the number of complete process...

I believe that most consumers have heard that the life of a lithium battery is "500 times", 500 times of charge and discharge, beyond this number, the battery will "end of life", many friends in order to be able to extend the battery life, every time The battery is charged only when it is completely exhausted. Does this really extend the life of the battery? the answer is negative. The life of a lithium battery is "500 times", which does not refer to the number of times of charging, but a cycle of charging and discharging. The so-called 500 times means that the manufacturer has achieved about 625 charging cycles at a constant depth of discharge (such as 80%), reaching 500 charging cycles. (80%*625=500) (Ignore factors such as reduction of lithium battery capacity) However, due to various influences in real life, especially the depth of discharge during charging is not constant, "500 charging cycles" can only be used as a referenc...
