Novel sealant material for electrochemical cell components

摘要

Multipurpose sealing adhesive materials for sealing different components of an electrochemical cell are provided. The sealing materials are acid, acid anhydride, acid ester or metallocene modified polyolefins that are capable of providing multiple sealing functionalities in a heat activated sealing process. These sealing polymers are capable of adhering to plain and textured metal, graphite and graphite-filled polymer composite separator plates.
