Abstract
Negative electrodes consisting of Mm(0.9)Ti(0.1)Ni(3.9)Mn(0.4)Co(0.4)A l(0.3) (Mm, misch metal) alloy powder were modified using palladium (P d) and nickel-palladium (Ni-Pd). The crystal cell volume expansion was about 9.0% after coating with 10 wt.% Ni-Pd on the powder surface. Th e utilization efficiency of the discharge capacity of the alloy electr odes coated with Pd and 10 wt.% Ni-Pd increased. The high rate dischar geability was also significantly improved by coating with Pd and 10 wt .% Ni-Pd.
