摘要： An energy storage element includes a sealed housing and an electrode-separator assembly disposed therein. The housing includes a metallic cup-shaped housing part having a housing bottom, a circumferential side wall, and a terminal opening, and a lid assembly closing the terminal opening of the cup-shaped housing part. One edge of an anode current collector or of a cathode current collector is electrically connected to the housing bottom and another edge is electrically connected to a contact sheet metal member which is directly seated on this edge. The lid assembly includes a metallic cover plate and a terminal pole which is guided through an aperture in the cover plate and is electrically insulated from the cover plate. The terminal pole is seated directly on the contact sheet metal member and is connected thereto by welding. Furthermore, the terminal pole is electrically insulated from the cover plate by a cured potting compound.
