Battery cell assembly, battery cell and battery storage system with the same

Abstract

The present invention relates to a battery cell assembly for enclosing and electrically contacting an electrochemical active material (60), comprising a housing (10) and a positive pole element (20) with a connecting section (21) extending through a housing opening (12). According to the invention, a heat dissipation element (40) is arranged in the housing (10), which is in contact around the central housing opening (12) with an inner surface of the shoulder section (13) of the housing (10), wherein the heat dissipation element (40) is designed as a shaped body with a corresponding surface shape to the shape of the inner surface of the shoulder section (13) of the housing (10), preferably made of an electrically insulating material comprising at least particles of a ceramic material.
