| titleOfInvention | Method for preparing ternary material precursor by using positive and negative electrode materials of capacitive nickel-hydrogen power battery |
| abstract | The invention belongs to the technical field of ternary material precursor preparation, and particularly relates to a method for preparing a ternary material precursor by using a positive and negative electrode material of a capacitive nickel-hydrogen power battery. Adding the anode and cathode materials and an oxidizing sodium source of the capacitive nickel-hydrogen power battery into a sulfuric acid solution at the same time for leaching reaction, and filtering to obtain a filtrate and a filter cake; adding a cobalt source and a manganese source into the filtrate, adjusting the pH value, adding a fluoride, and filtering to obtain a filtrate; adding a precipitator into the filtrate, reacting, filtering, washing and drying to obtain the ternary material precursor. The invention takes the waste capacitive nickel-hydrogen power battery as the raw material, has low cost, high product quality and good economical efficiency, and realizes the directional circulation of nickel-cobalt resources. |
