Fabricating of Lithium-battery-grade Precursor Salt Cobaltous Carbonate

摘要：

Some factors affect precursor capability, for example: raw material CoCl2 solution impurity, feeding methods of reactants, solutions pH value of deposition reaction, washing conditions, etc. Cobalt chloride is chosen as raw material, sodium carbonate as precipitator, cobalt ion concentration 65-70g/L, Cobalt chloride/ sodium carbonate(mol ratio)among 0.63～0.72,the way adding solution is chosen that precipitator is added to cobalt chloride solution, precipitated pH is chosen among 9.0-9.5.Under such conditions, better precursor can be acquired.
