NICKEL-METAL HYDRIDE BATTERY |
摘要 |
A positive electrode plate (3) of a nickel-metal hydride rechargeable cell contains nickel hydroxide particles (18), a coating layer (19) covering at least a part of a surface of each nickel hydroxide particle (18) and mainly composed of a cobalt compound having an average valence of cobalt more than 2, and Nb-based particles (15) and Y-based particles (16) distributed among the nickel hydroxide particles (18). A negative electrode plate (4) contains a hydrogen storage alloy having a Co content of equal to or less than 2.0% by mass, a separator (5) contains fiber having a sulfo group, and an alkaline electrolyte solution contains sodium hydroxide as a main solute. |
