POSITIVE ELECTRODE COMPOSITION FOR SECONDARY BATTERY, PROCESS FOR PRODUCTION THEREOF, AND SECONDARY BATTERY USING POSITIVE ELECTRODE COMPOSITION FOR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a secondary battery in which the coefficient of use of a positive electrode active material is improved and the amount of a raw material for an active material is reduced, and which can be produced at a low cost and has a reduced weight.

SOLUTION: A positive electrode composition for a secondary battery comprises a kneading product produced by kneading a raw material for an active material mainly composed of a metal oxide with a carbon and a silica porous material, wherein the kneading product has a bulk density of 2.6×10-1ml/g or more after the kneading product is filled in a grid-like current collector or applied on a sheet-like current collector and the filled or applied kneading product is dried and before the dried kneading product is chemically converted.
