Production method of sintered-type nickel positive electrode for alkaline secondary battery |
摘要 |
The following steps are conducted: preparing a metal salt carried-substrate A by soaking a sintered nickel substrate in an acidic solution containing cobalt ions and at least one metal ions of magnesium ions, iron ions and manganese ions, and drying thus soaked substrate; preparing a hydroxide carried-substrate B by soaking the substrate A in an alkaline solution to deposit cobalt hydroxide and at least one metal hydroxide of magnesium hydroxide, iron hydroxide and manganese hydroxide in the pores and on the surface of the substrate A; obtaining an oxide carried-substrate C by oxidizing the cobalt hydroxide to produce cobalt oxide having a mean cobalt valence of over 2; and obtaining an active material carried-substrate D by soaking the substrate C in a solution containing nickel nitrate dissolved therein, drying thus soaked substrate C, and then soaking thus dried substrate C in an alkaline solution, to fill the active material in the substrate C.
