Abstract
An improved battery having an electrolyte permeable porous inherently sealable separator and intercell connector both extending beyond the periphery of the cell electrodes. A polymeric film material separator seals the intercell connector. The separators may extend beyond the intercell connectors and are sealed to adjacent separators.
Claims6
An improved battery comprising in combination
- a. at least one cell, each cell comprising the combination of
- 1. a positive electrode,
- 2. a negative electrode, and
- 3. an electrolyte permeable separator between the electrodes, the separator extending beyond the periphery of the electrodes;
- and
- b. an intercell connector between each adjacent pair of cells, the connector extending outwardly beyond the periphery of the cell electrodes;
- wherein the improvement comprises having each electrolyte permeable separator consisting essentially of nonconductive, porous, inherently sealable polymeric film material and sealing the separator around its perimeter to the intercell connector, without applying an adhesive material to the surface of the separator periphery, to form a liquid and electrolyte impervious seal.
