Lithium-ion battery, commonly known as "lithium battery", is the battery system with the best comprehensive performance.

The intuitive difference between the 18650 lithium battery and the soft-packed lithium battery is that the 18650 lithium battery is a cylindrical steel shell battery with basically the same size, while the soft-packed lithium battery may have any shape and size.

There is no battery leakage problem, the battery does not contain liquid electrolyte, and uses colloidal solids.

Polymer lithium-ion battery, a new type of battery with higher energy density, miniaturization, thinning, light weight, high safety, long cycle life and low cost.

The soft-pack polymer lithium battery is safer because it uses a solid electrolyte, which will not leak and explode, but will only expand.

Suitable temperature, anti-cold and heat. The best use of the ambient temperature is about 25 °, because the ambient temperature is too high, the battery will be overcharged and gas is generated, and the ambient temperature is too low, the battery is undercharged.
