Abstract
A current collector for electrical storage device includes a sheet-shaped conductive substrate and a coating layer disposed on one or both sides of the conductive substrate. The coating layer includes a powdery carbon material, acid-modified polyvinylidene fluoride and polyvinylpyrrolidone. The content of the polyvinylpyrrolidone is 0.099 to 5.0 mass %. The content of the powdery carbon material in the coating layer is 15.0 to 45.0 mass %. Also disclosed is a coating liquid for producing the current collector for electrical storage device as well as a method for producing the current collector for electrical storage device.
