Fabricating of Lithium-Battery-Grade Precursor Salt Cobaltous Carbonate

Some factors affect precursor capability, for example: raw material CoCl 2 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...

Zusammenfassung:Some factors affect precursor capability, for example: raw material CoCl 2 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.
