PURPOSE:To provide a new negative active material alloy for an alkaline storage battery and a new negative active material electrode, which is an active material alloy completely different from conventional cadmium, and has high energy density, high discharge capacity, high quick charging capability, and long cycle life. CONSTITUTION:Alloy powder containing 20-50atom.% of a transition metal which is in a transition element series and has unfilled or half-filled (d) orbit and has internal paired (d) electrons, and having a particle size of 100mum or less is used as a new negative active material alloy for an alkaline storage battery. The alloy powder is mixed with 4-10wt.% polytetrafluoroethylene powder based on the weight of the alloy powder, and the mixture is press-molded to form a new negative active material alloy electrode. Boron, silicon, aluminum oxide, or silica may be contained. |
