| 简介 |
Low temperature discharge capability and high rate discharge capability are improved in an alkaline storage battery that uses as its negative electrode a hydrogen-absorbing alloy electrode employing hydrogen-absorbing alloy particles containing at least nickel and a rare-earth element. An alkaline storage battery uses as the negative electrode a hydrogen-absorbing alloy electrode employing hydrogen-absorbing alloy particles containing at least nickel and a rare-earth element. The hydrogen-absorbing alloy particles have a surface layer and an interior portion, the surface layer having a nickel content greater than that of the interior portion, and nickel particles having a particle size within a range of from 10 nm to 50 nm are present in the surface layer. |
