摘要:
A hydrogen absorbing alloy electrode contains an alloy which comprises particles A of a first hydrogen absorbing alloy and particles B of a second hydrogen absorbing alloy of a composition different from the composition of the first alloy joined to the particles A, with a joint layer C formed at the resulting joint interfaces and having a new composition containing the component elements of the first and second alloys. In a specific embodiment, particles A of a first hydrogen absorbing alloy having a CaCu.sub.5 -type structure are joined to particles B of a second hydrogen absorbing alloy having a Zr--Ni Laves-phase structure. In another embodiment, particles A of a first hydrogen absorbing alloy having a CaCu.sub.5 -type structure are joined to particles B of a second hydrogen absorbing alloy having a CaCu.sub.5 -type structure and different form the first alloy in composition. In another embodiment, particles A of a first hydrogen absorbing alloy having a Zr--Ni Laves-phase structure are joined to particles B of a second hydrogen absorbing alloy having a Zr--Ni Laves-phase structure and different from the first alloy in composition.
