Document Type and Number:
Japanese Patent JP2762669
Kind Code:
B2
Abstract:
PURPOSE:To manufacture a hydrogen storage Ni-Zr series alloy having an MgZn2 type crystalline structure by incorporating specified ratios of Zr, Ti, Mn, Fe, Co, W and Al into Ni. CONSTITUTION:An Ni-Zr series alloy contg., by weight, 10 to 37% Zr, 5 to 30% Ti, 5 to 30% Mn, 1 to 30% Fe, 0.5 to 20% Co, 0.01 to 15% W and 0.01 to 5% Al, contg., at need, 0.1 to 16% Cu and/or 0.1 to 15% Cr and the balance Ni with inevitable impurities is prepd. In this way, the hydrogen storage Ni-Zn series alloy having an MgZn2 type crystalline structure (a hexagonal C14 type crystalline structure) and particularly suitable for using as the negative active material of a closed type Ni-hydrogen storage battery can be obtd.
