The total molar concentration of soluble nickel salts, soluble ferric salts and soluble manganese salts can be 2mol/l, 2.1mol/l, 2.2mol/l, 2.3mol/l or 2.4mol/l. The growth rate and quality of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC precipitation crystals can be controlled by controlling the concentration of the solution. s2: Prepare a second solution consisting of an alkaline precipitator and a soluble carbonate.
Alkaline precipitators are used to provide hydroxide ions so that nickel, iron and manganese ions form hydroxide coprecipitates with hydroxide ions respectively (i.e., nickel-iron-manganese base precursor precipitates). Soluble carbonate is used to provide doped carbonate ions for the lattice of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC hydroxide coprecipitate.
Doping of carbonate ions can effectively improve the morphology and agglomeration mode of hydroxide coprecipitate (i.e. the precipitate of nickel-iron-manganese based precursor). Carbonate ions occupy a large space in the lattice of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC hydroxide coprecipitate. The hydroxide coprecipitate produced a certain amount of loose voids, which was conducive to the diffusion of sodium plasma phase in the sintering process of mixed sodium carbonate.
