Classification of lithium batteries.

32650 (32700) lithium battery

Square lithium batteries usually refer to aluminum or steel shell square lithium batteries, widely used in exploration and mapping, medical equipment, and portable testing equipment.

2. Classification by shell
Steel shell lithium battery
Early lithium-ion batteries are mostly made of steel shells. Due to the heavy weight and poor safety of the steel shell, the stability of the steel is strong. In the later stage, many manufacturers optimize the design structure through safety valves, PTC and other devices, greatly increasing its safety performance. And some directly replace the steel shell and use aluminum shell and soft package, such as the current mobile phone battery.

Aluminum shell lithium battery
Aluminum shell lithium-ion batteries are lighter in weight and slightly safer than steel shell lithium-ion batteries.

Flexible packaging lithium batteries
Flexible packaging lithium-ion batteries are gradually expanding their market share due to their advantages of light weight, low mold cost, and high safety.
