Abstract：The properties and performance of ABs hydrogen storasge alloy were described in the views of the alloy types, construction and the mechanism of hydriding/dehydriding; The development of substituent elements investigation was reviewed; The factors that affect the alloy performance were analyzed, such as cooling speed, annealing, pulverizing, mechanical alloyage, the encapsulation, fiuoration, hot alkali treatment and acid treatment which can improve the alloy properties were discussed in details; The effects of conductive additives, surface active agent or other additives which were added in the alloy powder or electrode were also introduced. The hydrogen storage capability of AB5 hydrogen storage alloy was increased from 250 mAh/g to 325 mAh/g. The capacity of cell was increasecl from 1.0 Ah to 1.5 Ah.
