PURPOSE:To manufacture an alkaline storage battery with the reduced content of Hg that suppresses the generation of H2 gas from a cathode material by using the Zn powder amalgamated with an alloy consisting of Pb, in, and Hg as a cathode active material for the battery. CONSTITUTION:Zn powder is thrown into a KOH aqueous solution and is pre- agitated. Then the Zn alloy amalgamated by pre-mixing Pb, In, and Hg is agitated while it is slowly being dropped into the said solution from a narrow hole. Subsequently, Zn-Pb-In-Hg powder is obtained by washing thus obtained alloy powder with water and drying it at low temperature and is used as a cathode active material. As a result, an alkaline storage battery with excellent performance that suppresses the generation of gas can be obtained. |
