The 18650 battery cell is a standardized cylindrical lithium-ion rechargeable battery. With its mature manufacturing process, high consistency, and cost-effectiveness, it serves as a core power supply component in consumer electronics, power storage, and other fields. Its model is directly named after its physical dimensions, featuring a wide range of application scenarios and clear technical characteristics.

Soft-pack Lithium batteries, also known as pouch batteries or soft-pack cells, are a crucial category of Lithium batteries. Their core distinction from traditional hard-case batteries lies in the use of aluminum-plastic composite film as the outer casing, rather than rigid materials such as steel casings and aluminum casings.

CCA stands for “Cold Cranking Amps.” Its value indicates the strength of a motorcycle battery’s ability to start an engine in cold temperatures.

Its core structural feature lies in the adoption of lithium cobalt oxide (LiCoO₂) as the positive electrode material, while graphite is typically used for the negative electrode.

Currently, the mainstream types can be divided into six major categories, with significant differences in key indicators such as energy density, safety, and cycle life.
