PURPOSE:To improve the charging and discharging cycle life of an alkaline storage battery and the utilization factor of an active material by mixing powder mainly composed of cadmium oxide with the powder of nickel and nickel hydroxide. CONSTITUTION:5 weight parts of nickel powder and 1 weight part of nickel hydroxide powder are mixed with 100 weight parts of cadmium oxide. Then, 16 weight parts of ethylene glycol are added to a product obtained from the aforesaid mixing process and sufficiently kneaded, thereby obtaining a paste product. A nickel fiber sintered compact is filled with the aforesaid paste product and dried, thereby obtaining a cadmium negative electrode of the prescribed thickness. As a result, conductivity between active matertal particles is increased due to the nickel powder and fine nickel hydroxide particles act as cores in a precipitation process for the uniform dispersion of the active material particles. According to the aforesaid construction, the charging and discharging cycle life of the alkaline storage battery is improved and the utilization factor of the active material can be in creased. |
