Prismatic cell housings for future applications in the automotive industry

Prismatic battery cells are becoming increasingly important, particularly in the automotive industry. However, established manufacturing processes for the cell housing, such as deep drawing, are not suitable for all current designs of prismatic cells. This article presents and compares current designs of prismatic cells together with possible manufacturing processes. In addition, possible future developments are shown to add functionalities or reduce the cost of the cell housing, such as cell-integrated sensors or integrated safety valves.
