  • Battery constructions having increased internal volume for active components
    Patent number: 6670073
    Abstract: An electrochemical cell constructed in accordance with the present invention includes a can for containing electrochemical materials including positive and negative electrodes and an electrolyte, the can having an open end and a closed end; a pressure relief mechanism formed in the closed end of the can for releasing internal pressure from within the can when the internal pressure becomes excessive; a first outer cover positioned on the closed end of the can to be in electrical contact therewith and to extend over the pressure relief mechanism; a second outer cover positioned across the open end of the can; and an insulator disposed between the can and the second outer cover for electrically insulating the can from the second outer cover. According to another embodiment, the second cover is dielectrically isolated from a current collector.
    Type: Grant
