PROBLEM TO BE SOLVED: To obtain a battery with a drastic improvement both in a charging speed and a discharging speed. SOLUTION: A fibrous hydrogen storage alloy is used as a negative electrode for a nickel hydride battery. Here, the fibrous hydrogen storage alloy in a shape of an unwoven fabric or a fabric, a plurality of fibrous hydrogen storage alloys in a bundle, or the like, can be used as an electrode. The battery using the fibrous hydrogen storage alloy is structured, for instance, of a positive electrode with carbon fiber with its surface coated with nickel/nickel hydride arrayed piece by piece or bundle by bundle or made into a woven or an unwoven fabric, and a negative electrode with the fibrous hydrogen storage alloys arrayed piece by piece or bundle by bundle or made into a woven or an unwoven fabric laminated with a separator between, to which, a positive electrode collector is fitted so that at least one end of a fibrous matter laid out as the positive electrode comes in contact and a negative electrode collector is fitted so that at least one end of the fibrous hydrogen storage alloys laid out as the negative electrode comes in contact and with electrolyte solution filled in cells.
