| Abstract: |
| Waste asymmetric capacitor battery was recycled by stepwise leaching. Effects of temperature, reaction time, dosage of sulfuric acid, amount of oxidant, and order of adding on leaching rate were studied. The process of waste battery recycling was put forward including sulfuric acid leaching of waste battery material, rare earth precipitation, removal of Mg and Ca, concentration adjustment, preparation of ternary cathode material precursor by precipitation, preparation of ternary cathode materials, and battery assembling. |
