PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC Magnetic preparation method By preparing the first solution including mixed salt, so that the mixed salt can be added to the reaction vessel at the same time to uniformly generate co-precipitation of nickel hydroxide, ferric hydroxide and manganese hydroxide. It can also avoid increasing the number of equipment related to the production line of nickel-iron-manganese based precursors.
By preparing a second solution of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, which includes soluble carbonate and alkaline precipitator, the coprecipitation reaction of soluble carbonate and alkaline precipitator occurs at the same time, so that the carbonate ions are uniformly doped in the hydroxide coprecipitate lattice. The doping of carbonate ions can effectively improve the morphology and agglomeration mode of hydroxide coprecipitates (i.e. the precipitates of nickel-iron-manganese based precursors).
Carbonate ions occupy a large space in the lattice of hydroxide coprecipitate, which makes the hydroxide coprecipitate produce a certain amount of loose space, which is conducive to the sintering of mixed sodium carbonate and the diffusion of sodium plasma phase in the process of iron removal by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
