Failure classification and cause analysis of lithium battery.
1、 Capacity decay failure
During the standard cycle life test, the discharge capacity shall not be less than 90% of the initial capacity when the number of cycles reaches 500. Or when the number of cycles reaches 1000, the discharge capacity shall not be less than 80% of the initial capacity. If the capacity drops sharply within the range of standard cycles, it belongs to capacity attenuation failure.

Everything You Need to Know About the 18650 Battery
This post tells you everything you need to know about 18650 batteries. We'll talk about different types, features, charging, lifespans, and our recommendations for batteries and chargers.
An 18650 is a lithium ion rechargeable battery. Their proper name is “18650 cell”. The 18650 cell has voltage of 3.7v and has between 1800mAh and 3500mAh (mili-amp-hours).
18650s may have a voltage range between 2.5 volts and 4.2 volts, or a charging voltage of 4.2 volts, but the nominal voltage of a standard 18650 is 3.7 volts.
