Battery Cell having a Prismatic or Cylindrical Housing, Battery Module and Motor Vehicle

摘要

A battery cell, preferably a lithium ion battery cell, includes a prismatic or cylindrical housing with two opposite sides. The first side of the two opposite sides of the housing is partially or completely at cathode potential. The second side of the two opposite sides of the housing is partially or completely at anode potential. One of the two opposite sides additionally has a circumferential edge protruding partially or completely from the surface, while the other of the two opposite sides has a circumferential edge that is partially or completely recessed relative to the surface. The battery cell can be easily joined to other battery cells by stacking to form battery modules, making it possible to avoid expensive connecting techniques and production processes. The battery cell is included in a battery module and a motor vehicle that has an electric drive motor and a battery system.
