Title:
COMPOSITE POLYMER SOLID ELECTROLYTE AND NONAQUEOUS ELECTROCHEMICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/1997/018596
Kind Code:
A1
Abstract:
A composite polymer solid electrolyte prepared by impregnating a unicellular polymer foam with an electrolyte. A polymer matrix constituted of cell walls defining closed cells is impregnated with a nonaqueous electrolyte, continuous solid-phase domains are formed and the closed cells are substantially filled with the nonaqueous electrolyte. A nonaqueous electrochemical device, such as a nonaqueous cell, components for a voltaic cell like electrodes, etc., using the solid electolyte are disclosed. The solid electrolyte has a high ionic conductivity and a high mechanical strength. The nonaqueous solution in the closed cells hardly leaks. Therefore, the nonaqueous electrochemical device using the solid electrolyte has an excellent electrochemical performance and an excellent electrolyte holding property, and is extremely high in reliability and safety.
