| Abstract: | Rare-earth-based ABs-type hydrogen storage alloys are widely used as cathode materials of MH-Ni batteries for their advantages, such as, lower price of raw material, good properties in low temperature and excellent high-rate discharge capacity. Recent research development on influence factors of discharge capacity of rare-earth-based hydrogen storage alloys, including composition, preparing methods, work temperature and other methods, was reviewed. Currently, the main problem existing in low discharge capability of rare-earth -based hydrogen storage alloy is mentioned. |
