SHEET ELECTRODE/ELECTROLYTE STRUCTURAL BODY

摘要

PROBLEM TO BE SOLVED: To attain a large current discharge so as to improve a discharge rate characteristic, when used as a secondary battery by improving the ion conductivity inside an electrode. SOLUTION: This is a sheet electrode/electrolyte structural body, in which a gel electrolyte 3 is interposed between a positive electrode 1 and a negative electrode 2. An electrolyte storage layer 4 is provided around the positive electrode 1 and the negative electrode 2. The electrolyte storage layer 4 is gelled by impregnating an electrolyte in a high-polymer matrix and is joined to each boundary of the positive electrode 1 and the negative electrode 2 which is opposite to the gel electrolyte 3 side.
