Battery solitary cell for use in traction battery for partially electrically driven vehicle, has electrode stack, electrically insulating frame and two sheath plates which are connected with one of poles of electrode stack

摘要

The battery solitary cell (1) has an electrode stack (5), an electrically insulating frame (2) and two sheath plates (3,4) which are connected with one of the poles of the electrode stack. The electrically insulating frame is formed of polypropylene. An intermediate layer (10) formed of modified polypropylene is arranged between the electrically insulating frame and the sheath plates. The modified polypropylene is formed as a film. The battery solitary cell is formed in lithium-ion technology.
