A misch-metal hydrogen-storage alloy consisting of a homogenous CaCu5 phase with grain size less than 50 nm was prepared by rapid quenching between double rollers. The specific capacity of alloy reached 295 mAh/g during charge and discharge with 200 mA/g. The attenuation of capacity was 4.5% after 200 cycles. The charging capacity of a battery made from this alloy powder was up to 547.4 mAh/g after 2 cycles discharge with a Couloumb. The attenuation of capacity was 2.48% after 95 cycles.
