ELECTRODE ACTIVE MATERIAL LAYER FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide means capable of improving cycle characteristics of a battery by relaxing stress due to expansion/contraction of an active material in an electrode.SOLUTION: Disclosed is an electrode active material layer 1 for a nonaqueous electrolyte secondary battery which includes a fibrous resin skeleton base material 3 and an active material 5 and is formed by dispersing the active material 5 into a void of the fibrous resin skeleton base material 3. The content of the fibrous resin skeleton base material 3 is 0.1-10 mass% to the active material 5, the fibrous resin skeleton base material 3 has conductivity, and resin fiber constituting the fibrous resin skeleton base material 3 is 0.1-100 μm in the diameter.SELECTED DRAWING: Figure 1
