Under continuous nitrogen protection, the third solution is injected into the reaction vessel, and the first solution is gradually injected into the reaction vessel at the injection rate of 15ml/min. At the stirring rate of 800rpm and 50℃, the second solution is injected into the reaction vessel to maintain the ph of the reaction solution between 11 and 12, and the co-precipitation reaction is carried out. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal of iron.
After the first solution is injected, the supernatant is standing, and the supernatant is drained until the particle size dv50 of the nickelfer-manganese base precursor precipitates to the target value of 5.6μm, and the obtained nickelfer-manganese base precursor precipitates after washing and drying, and na2co3 is prepared according to the ratio of x = 0.75. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal of iron.
After mixing, the electrode MATERIAL of the sodium-ion battery was obtained by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field after sintering at 850℃ for 12h in a horse fluorine furnace with a continuous flow rate of 10l/min in an air atmosphere. 2mol/l of the first solution; A second solution containing 3.78mol/l naoh and 0.42mol/l sodium carbonate was prepared. A third solution containing 3g/l ammonia and 0.2ml/l hydrazine hydrate was prepared;
