MANUFACTURING METHOD OF BATTERY NONWOVEN FABRIC BOARD AND BATTERY ELECTRODE AND BATTERY USING THE BOARD

摘要

PROBLEM TO BE SOLVED: To provide a battery electrode which has a low internal resistance of a battery, an excellent discharging property (a voltage utilization ratio at high rate discharging) and is causing no over-charging while charging and hardly gets a damage on a plated film due to expansion and compression of the electrode accompanying charging/discharging and has an excellent cycle property.

SOLUTION: The battery electrode board is composed of a resin nonwoven fabric on the fiber surface of which a nickel containing metal is coated, and a fineness of the fiber is 2.2 to 6.7dTex, and a film thickness of the coated metal is 2 to 12 μm. A material of the fiber is preferably made of polypropylene and polyethylene.
