HYDROGEN-STORED ALLOY ELECTRODE

PURPOSE: To obtain an electrode by which the inner pressure of a closed-type alkali battery is lowered, the capacity and cycle life is improved, and the activation time is reduced to 3-5 hours. CONSTITUTION: An electrode is formed by a composite of hydrogen storage alloy powder, having comparatively...

Zusammenfassung:	PURPOSE: To obtain an electrode by which the inner pressure of a closed-type alkali battery is lowered, the capacity and cycle life is improved, and the activation time is reduced to 3-5 hours. CONSTITUTION: An electrode is formed by a composite of hydrogen storage alloy powder, having comparatively high electrochemical capacity with a formula: MmNi5- X- Y- ZAxByCz and a hydrogen-absorbing alloy with catalytic activity expressed by a formula: D2-u F1-v FuGv. Here, Mm is a mesh metal, A is Co, Cr, V and B is Mn, Sn and Be, C is Al, Ca, Mg, Zr and Nb, D is Mg, Al, E is Cu, Zn F is Ca, Be, and G is Sn, Bi. X is 0
