LOW PROFILE VENTABLE SEAL FOR AN ELECTROCHEMICAL CELL

摘要

An electrochemical cell having a low profile seal assembly for sealing the open end of the cell container. The seal assembly includes a support member having a surface area that covers substantially the open end of the cell container and has a plurality of openings therein. A seal member is disposed against the support member to provide a sealed closure to the open end of the cell container. The seal member has a membrane with a groove formed in a surface thereof which acts as a stress concentrator. The groove is located against the support member such that said groove is located adjacent to the openings formed in the support member and is further supported by the support member at other locations.
