Cylindrical Cell Structure

Cathode: The main cathode materials are LiCoO2, LiMn2O4 or (LiFePO4). The material of the positive electrode determines the voltage and performance of the battery.
Anode: The anode material is mainly graphite or silicon.
Electrolyte: Electrolyte is the conductive medium between the positive and negative electrodes, usually a liquid or gel.

 

Casing: The casing of the battery cell is a metal cylinder, usually made of aluminum or steel, used to protect the internal structure of the battery, provide mechanical support, and prevent the impact of the external environment on the battery.
Seal: The sealing part of the battery cell is located on the top of the casing and is used to seal the battery and prevent electrolyte leakage.
