An AB5 type alloy, La0.75Ce0.25Ni3.46Al0.17Mn0.04Co1.33,was successfully prepared via partial substitution of Ce for La and Al, Mn, Co for Ni, respectively. The structure, morphology, and chemical composition of the as-obtained alloy powders were care-fully examined by X-ray diffraction, scanning electron microscopy equipped with energy dispersive X-ray spectroscopy. Electro-chemical properties of the hydrogen storage alloy were systematically investigated in standard 29 Ah Ni-MH batteries. The 29 Ah Ni-MH battery exhibited a theoretical discharge capacity of 29 Ahat 1 C. The capacity retention was 99% after 2000 cycles. Fur-thermore, excellent low temperature performance of this hydrogen storage alloy was obtained at?25 oC. And the results showed that it exhibited not only high discharge capacity (21 Ah at?25 oC and 1 C), excellent high current densities instantaneous discharge performance (discharge 0.9 Ah in 10 s at 12.5 C rate and the voltage could be maintained around 0.73 V), but also remarkable high-rate discharge capacity (discharge 17.7 Ah at 50% SOC and 6.25 C, and the voltage could be maintained around 0.95 V).
