18650 lithium battery is a commonly used lithium-ion battery in electronic products, often used as a battery cell in laptop batteries.
The common 18650 lithium batteries are divided into lithium-ion batteries and lithium iron phosphate batteries. Lithium ion batteries have a nominal voltage of 3.7V and a charging cut-off voltage of 4.2V.
SOH refers to the capacity, health, and performance status of a battery. Simply put, it is the ratio of performance parameters to nominal parameters after a period of use.
The production of lithium batteries used to be Japan's strong point, but now the rise of Chinese and Korean companies has attracted worldwide attention.
The most important step in the charging and discharging process of lithium battery packs is the balancing step, which requires protection against charging overvoltage,
Lithium battery packs, due to their inherent characteristics, do not have memory effects and can be charged and discharged at will. However, why are there still so many accidents of lithium battery explosions and bulges?
Power batteries are mainly used for energy storage, with large capacity, long lifespan, and low self discharge. Electric tool batteries have a small capacity and do not require high power output;
The difference between lithium battery capacity and battery rated capacity. What is the difference between lithium battery capacity and rated capacity?
