Laminating structure of primastic case batteries:

 Assembly processes:

The assembly process mainly consists of casting anode and cathode plates and placing a separator between the anode and the cathode.

There are two different electrode structures used depending on the types of casing, a stacked structure for prismatic cells and a spiral wound structure for cylindrical cells

If a slim pack is desired, prismatic cells are often used to optimize the use of space for high capacity battery applications.

The manufacturing process uses a stacked electrode structure where cutting of anode and cathode foils is required to stack electrode plates with a separator sandwiched between the anode and cathode.

   While optimization of the use of space is achieved, the design is disadvantaged by more complexity and subsequently higher manufacturing costs due to the fact that stacked electrode plates require a clamping mechanism to connect all anodes/cathodes together to the main terminal post.
