PURPOSE:To rapidly produce a conjugated oxide for a cell easy for refining with a simple process by dripping a mixed solution of Ag salt and Ni salt into an alkaline aqueous solution and by wet oxidizing the obtained coprecipitate with an oxidant. CONSTITUTION:A mixed solution of silver salt mainly made of silver nitrate and Ni salt selected among nickel nitrate, nickel sulfate, and nickel acetate, etc. is dripped into an alkaline aqueous solution little by little while being well stirred. Then, Ag2O and Ni(OH)2 are infinitesimally mixed together and are coprecipitated in a gel status. The gel-like coprecipitate thus obtained is wet oxidized with an oxidant as it is in the alkaline aqueous solution, thereby AgNiO2 can be easily produced. Salt persulfate, H2O2, or O3, etc. can be used for the oxidant. The AgNiO2 obtained is washed with distilled water and is dried under heat to make up refined AgNiO2. |
