| 简介 |
A sealed nickel metal-hydride battery shows a high output density and an excellent cycle performance particularly in a cold atmosphere. In a nickel metal-hydride battery having a nickel electrode and a hydrogen absorbing electrode respectively as positive electrode and negative electrode, the hydrogen absorbing electrode is formed by making an conductive support carry hydrogen absorbing alloy powder of rare earth elements and non-rare earth elements including nickel and the saturation mass susceptibility of the hydrogen absorbing alloy powder is 2 to 6 emu/g while the rate at which the hydrogen absorbing electrode carries hydrogen absorbing alloy powder per unit area is 0.06 to 0.15 g/cm2. |
