PURPOSE:To form a hydrogen storage electrode by mixing an additive, which generates hydrogen by reacting with solution, into a hydrogen storage alloy and steeping the mixture into solution and activating the hydrogen storage alloy with generated hydrogen, and thereafter forming the mixture into an electrode shape. CONSTITUTION:An additive is made of aluminum or nickel or raney alloy etc., which generates hydrogen by dissolving by itself in alkaline solution etc., and is mixed into a hydrogen storage alloy composed of an alloy which is made of both elements, one combines easily with hydrogen such element as Ca etc. and the other is difficult to combine with hydrogen such element as Al etc., and a mixture is steeped into alkaline solution and stirred so as to hydrogenate and activate the hydrogen storage alloy with generated hydrogen and the mixture is washed and a binding agent such materials as polyethylene etc. is added thereto and said mixture is formed by compressing into bunching metal or foaming metal etc. which is a collector material, and is foamed into a hydrogen occulusion electrode which makes a negative electrode of an alkaline storage battery. Therefore, an electrode with good characteristics can be obtained by simple method. |
