SECONDARY BATTERY
Document Type and Number:
Japanese Patent JPH1186855
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a battery which uses V2 O5 aerogel as a neagative electrode active material and has high-energy density and is superior in a cycle characteristic. SOLUTION: A battery is constituted, by respectively using a complex of V2 O5 aerogel and a soluble conductive high polymer as a positive electrode active material and a gel-like high polymer solid electrolyte as an electrolyte. When a beaker cell is manufactured, a positive electrode is manufactured by press-fitting this to a SUS 304 wire net by mixing/kneading V2 O5 aerogel, acetylene black, graphite and polytetrafluoroethylene. The electrolyte is prepared by a nonaqueous solvent solution (an electrolytic solution) of LiPF6 and the gel-like high polymer solid electrolyte. This gel-like high polymer solid electrolyte is manufactured by having ultraviolet rays irradiated to a solution by mixing the electrolytic solution, ethoxydiethylene glycol acrylate, trimethylolpropane triacrylate, benzoin isopropyl ether.
