| 摘要 |
The invention relates to sealant materials for sealing interfacial spaces within electrochemical cells. The sealant material is a thermoplastic block copolymer elastomer characterized by having at least two glass transition temperatures. The thermoplastic block copolymers form particularly useful sealants for a current collector nail which is inserted through an insulating closure member, such as a plastic grommet, used to close the open end of the cell.
