CURRENT COLLECTOR AND SEAL ASSEMBLY FOR ELECTROCHEMICAL CELL

摘要

A current collector and seal assembly for use in an electrochemical cell is provided. An electrochemical cell comprises a container generally having a closed bottom end, an open top end, and side walls extending between the top and bottom ends. Electrochemically active materials are disposed in the container, and generally include a positive electrode and a negative electrode. A current collector and seal assembly is provided to close the open end of the container and includes a resilient and electrically non-conductive seal body having an upstanding wall defining an opening therethrough. A current collector is inserted through the opening and into one of the electrochemically active components. A polymeric compression bushing compresses the upstanding wall so that the collector and compression bushing cooperate to exert radial compressive stress and tangential compressive stress on the upstanding wall after insertion of the current collector through the opening.
