Abstract
A sealing grommet in a cylindrical electrochemical cell designed for long term use, the grommet having an extended area which is compressed between a separator having structural integrity and a cell top.
Claims8
A cylindrical electrochemical cell comprising an anode, a cathode, a separator having structural integrity therebetween, and an electrolyte, with said anode, cathode and separator being concentrically longitudinally axially disposed within a cell container having a closed bottom and an open top, said open top being closed by a cell top and an electronically insulative grommet positioned and compressively held between said cell container and said cell top, said cell top exerting a compressive force on an upper edge of said separator characterized by said grommet having an integral, radially inwardly directed portion compressively held between said separator upper edge and said cell top with a seal formed thereby.
