ELECTRODE SUBSTRATE FOR BATTERY, ELECTRODE FOR BATTERY, AND BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode substrate for a battery capable of enhancing battery capacity and discharge characteristics.

SOLUTION: The electrode substrate for the battery has metallic cover layers on fibers of a nonwoven fabric comprising resin fibers. The nonwoven fabric used for the substrate has a fineness of fiber of 1-7 dTex and a weight per area of fiber of 25-60 g/m2. The nonwoven fabric is heat-treated and the thickness after heat treatment is 0.5-1.0 mm. Preferably, the weight per area of metal is 150-300 g/m2, and porosity obtained from the thickness of the electrode substrate and weight per area of fibers and the weight per area of metal is 75-97%.
