Abstract:
A nickel-metal hydride storage battery includes a negative electrode containing a hydrogen storage alloy and an electrolyte solution. The hydrogen storage alloy has a CaCu5-type crystal structure and contains at least a Ni element and a rare earth element. The rare earth element is partly substituted with an Y element, and the electrolyte solution contains NaOH in an amount of 2.0 M or more.
