The co-precipitation reaction is carried out under the condition of continuous non-oxygen protective atmosphere, so as to avoid the oxidation of bivalent iron ions into trivalent iron ions during the co-precipitation reaction, and avoid the precipitation of some products of the co-precipitation reaction nickel-iron-manganese base precursor. Influence the width of particle size distribution of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field.
By inhibiting the oxidation of bivalent iron ions with a non-oxygen protective atmosphere and a reducing agent, homogeneous sheet particles can be obtained, and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field is formed by agglomeration of homogeneous sheet particles. The second solution is used to adjust the ph value of the coprecipitation reaction, and the injection amount and injection speed of the second solution can be adjusted according to the ph value of the reaction solution.
By maintaining the ph value of the co-precipitation reaction process in the range of 10.5 ~ 12, the consistency of the reaction conditions of the whole process of the co-precipitation reaction is ensured, so as to ensure the consistency of the morphology of the products of the co-precipitation of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field, that is, the uniformly sized flake particles are obtained.
