ABSTRACT:
There are disclosed a powdery material comprising a hydrogen-storing compound comprising a core layer of a hydrogen-storing alloy coated with a transition metal oxide layer and having a transition metal dispersed and carried on the outermost surface thereof, an electrode member for alkali secondary cells using the powdery material comprising a hydrogen-storing compound, and a secondary cell using the electrode member as an electrode. With such an alkali secondary cell, a strong resistance to overcharge, a high charging and discharging efficiency and a long cycle life can be implemented.
