Embodiment 1
[0022] (1) Add 0.04molNiSO 4 ·6H 2 O, 0.024molCoSO 4 ·7H 2 O, 0.016molMnSO 4 ·H 2 O was dissolved in 80ml of a mixture of deionized water and isopropanol, wherein isopropanol accounted for 10% of the volume of the mixture. Stir at room temperature until completely dissolved to prepare a ternary mixed solution of 1 mol / L. After dissolution, the molar ratio of Ni:Co:Mn is 5:3:2.
[0023] (2) Add 0.088mol of (NH 4 ) 2 CO 3 Dissolve in 160ml of a mixture of deionized water and isopropanol, wherein isopropanol accounts for 10% of the volume of the mixture. Stir at 30°C until completely dissolved to prepare a 0.55mol / L ammonium carbonate solution, and seal the container holding the ammonium carbonate solution to reduce the evaporation of water.
[0024] (3) After the above-mentioned heated ammonium carbonate solution is completely dissolved, quickly pour it into the ternary mixture, heat at 60°C with microwave and stir for 40 minutes.
[0025] (4) After aging the above-men...
