Under continuous nitrogen protection, the third solution is injected into the reaction vessel, and the 4l 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 was injected, the supernatant was standing, and the supernatant was drained until the particle size dv50 of the nickel-iron-manganese base precursor reached the target value of 9μm. After precipitation, washing and drying, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field was used to remove iron, and na2co3 was prepared with the first solution of 2mol/l at the ratio of x = 1.0. A second solution containing 4.116mol/l naoh and 0.084mol/l sodium carbonate was prepared.
A third solution containing 6g/l ammonia and 0.2ml/l hydrazine hydrate was prepared; After mixing, the sodium ion battery electrode MATERIAL was obtained from PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field by sintering at 880℃ for 12h in a horse fluorine furnace with a continuous flow rate of 30l/min in air atmosphere.
