SOLID POLYMER ELECTROLYTE, BATTERY AND SOLID-STATE ELECTRIC DOUBLE LAYER CAPACITOR USING THE SAME AS WELL AS PROCESSES FOR THE MANUFACTURE THEREOF

Document Type and Number:

WIPO Patent Application WO1994029884

Kind Code:

A3

Abstract:

A solid polymer electrolyte comprising a composite of: (a) a polymer comprising of at least one compound selected from the group consisting of 2-(meth)acryloyloxyethylcarbamic acid ester and (b) an electrolyte; an electrode comprising said polymer and an electroactive substance or polarizable material such as a polyaniline-based polymer soluble in organic solvent, other electroconductive polymers, metal oxides, metal sulfides and carbon materials as well as process for manufacturing the same; primary and secondary batteries having said solid polymer electrolyte as well as process for manufacturing the same; a solid-state electric double layer capacitor comprising said solid polymer electrolyte as well as process for manufacturing the same. The solid polymer electrolyte can be made into a thin film and has a high ionic conductivity. The battery has a high capacity, and a high current density and good cyclability. The electrode has a high electrochemical activity and flexibility. The electric double layer capacitor has a high output voltage and a large take-out current.
