Title:
NOVEL SOLID POLYMER ELECTROLYTE AND MULTILAYER ELECTROCHEMICAL ASSEMBLY COMPRISING SUCH A SOLID POLYMER ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO1999020677
Kind Code:
A8
Abstract:
The invention concerns a solid polymer electrolyte characterised in that it comprises a matrix formed, at least partially, of cross-linked polymer comprising units derived from ethylene oxide and units derived from ethylene oxide substituted with a reactive radical by substitution and whereof at least one part participates in the cross-linking bond, and at least an ionizable alkaline salt chelated in said matrix. The invention also concerns a multilayer electrochemical assembly (1) formed of a positive electrode (2) and of its current collector (6), of the negative electrode (3) and optionally of its current collector (5), said electrodes being separated by a solid polymer electrolyte (4) of the invention.
