PURPOSE:To suppress the generation of hydrogen by applying paste, which is composed mainly of one kind of cadmium oxide or cadmium hydroxide or metallic cadmium and includes antimony oxide or antimony hydroxide, to a conductive core body. CONSTITUTION:Antimony oxide such as antimony trioxide or tetraoxide or the like, or antimony hydroxide reacts with alkali, thereby producing highly- reductive antimonite such as potassium antimonite. Therefore, the antimonite is produced in a cadmium anode, to which active material paste including these materials as mentioned above is applied, by the injection of alkali electrolytic solution at the time of fabricating a battery. And cadimium hydroxide or cadmium oxide in the negative electrode is reduced. As a result, the conductive matrix of metallic cadmium can be formed in the anode in the battery and the highly active metallic cadmium can be prevented to oxidize in the air at the time of making the anode. |
