Abstract
A general purpose organic electrolyte cell usable for long-periods or usable after long periods of storage even in a high temperature environment exceeding 150.degree. C. The positive and the negative electrodes are separated by using a separator made of porous synthetic resin sheet having a melting point of at least 170.degree. C.
Claims4
An organic electrolyte cell, comprising:
- a positive electrode;
- a negative electrode comprising lithium;
- and
- an organic electrolyte comprising a solvent selected from the group consisting of an organic solvent and a mixed organic solvent, said solvent having a boiling point of at least 170.degree. C.;
- wherein the positive electrode and the negative electrode are separated by a separator made of porous synthetic resin sheet having a melting point of at least 170.degree. C. and a gasket consisting essentially of a thermoplastic synthetic resin having a continuously usable temperature of at least 150.degree. C. said gasket having a surface pre-coated with a sealant layer consisting essentially of blown asphalt, said gasket inserted between a metal container of positive polarity and a metal container of negative polarity, said metal containers sealed by curling the upper flange of one of said metal container of positive polarity and said metal container of negative polarity and by applying pressure on said gasket inserted between said metal containers.
