The safety testing of lithium batteries mainly includes the following aspects: it needs to pass safety tests such as overcharging, short circuit, needle puncture, squeezing,
How to maintain large capacity lithium batteries in winter: Lithium battery manufacturers share maintenance methods for electric vehicle batteries in winter:
The lifespan of lithium batteries is generally 300-500 charging cycles. Assuming a complete discharge provides 1Q of electricity, without considering the decrease in electricity after each charging cycle,
Lithium batteries can be divided into square lithium batteries (such as commonly used mobile phone batteries) and cylindrical batteries (such as 18650) according to their appearance;
26650 lithium battery is a type and specification of cylindrical lithium battery. Used in the fields of electric tools, lighting, wind and solar energy storage, electric vehicles, toys, instruments and meters,
18650 lithium battery is a standardized cylindrical lithium-ion battery named after its size specifications - diameter 18 millimeters (18mm) and length 65 millimeters (65mm),
What we usually refer to as "18650" actually refers to the external specifications of the battery, which is a standard battery model,
When assembling polymer lithium batteries, there are single assembly and multiple parallel and multiple intermediate assembly methods as needed.
