A manufacturing method of a hydrogen storing metal alloy, and a manufacturing method of the cathode for alkaline batteries

Japanese Patent JP6015642

B2

The principal purpose of the present invention is to provide a method for producing a hydrogen storage alloy that makes it possible to produce a hydrogen storage alloy having increased discharge capacity, and a method for producing an alkaline secondary cell electrode that makes it possible to produce an electrode for an alkaline secondary cell having increased discharge capacity. The present invention provides a method for producing a hydrogen storage alloy, the method having at least a step for preparing a mixture containing a hydrogen storage alloy having a body-centered cubic structure and an auxiliary agent containing Ni, and a step for sintering the prepared mixture at a temperature of 600-850°C while applying pressure of 32.34-715.4 kPa; and a method for producing an alkaline secondary cell electrode, the method having at least a step for preparing an electrically conductive porous electrode material and a mixture containing a hydrogen storage alloy having a body-centered cubic structure and an auxiliary agent containing Ni, and a step for sintering the prepared electrically conductive porous electrode material and mixture, in a state of contact, at a temperature of 600-850°C while applying pressure of 32.34-715.4 kPa.
