Title:
GEL HIGH-MOLECULAR SOLID ELECTROLYTE BATTERY AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2001110405
Kind Code:
A
Abstract:

To provide a gel high-molecular solid electrolyte battery which has a large discharge capacity and is superior in cyclic characteristic and low- temperature discharge characteristic, without having to newly add additives or substances.

In a gel high-molecular solid electrolyte battery comprising a positive electrode of lithium cobalt oxide, a negative electrode of carbon where a negative electrode activation substance layer mainly of a carbon material, that can absorb and emit lithium ions, is formed on a surface of a current collector body of the negative electrode, and a gel high-molecular solid electrolyte, a mixed density of lithium cobalt oxide in the positive electrode activation substance layer is from 2.35 to 3.2 grams per cubic centimeters, a thickness of the positive electrode activation substance layer is set from 37 to 97.8 micron meters, a mixed density of the carbon materials in the negative electrode activation substance is from 0.86 to 1.70 grams per cubic centimeters, and the thickness of the negative electrode activation substance layer is set from 35 to 92 micron meters.
