Assembly Process
Cathode and anode electrode sheets, completed through the electrode process, are assembled into battery cells by integrating them with other key battery components: separators and electrolytes.
The assembly process may vary depending on the battery cell's form factor and the manufacturer's technology.
Prismatic Cell
Prismatic batteries are renowned for their exceptional structural safety.
Their robust form factor ensures high resistance to physical damage, even in the event of collisions or external impacts.
Additionally, prismatic batteries must efficiently dissipate heat generated internally in order to prevent performance degradation and a shortened lifespan.
