METHOD OF PRODUCING THE SPHERICAL PRECURSOR CONTAINING LITHIUM IONS AS CATHODE MATERIAL FOR LITHIUM-ION BATTERY

摘要

A method of producing the spherical precursor containing lithium ions as cathode material for lithium-ion battery, which includes the following steps. The metal salts containing lithium ions and acid radicals and water are thoroughly mixed to form an aqueous metal salt solution containing lithium ions. The aqueous metal salt solution containing lithium ions is fed into the hot-blast furnace chamber for the high temperature spray granulating equipment, and the atomizer sprays the aqueous metal salt solution containing lithium ions in the hot-blast furnace chamber, so as to form spherical liquid drops in particle size of 0.1 μm to 20 μm. The hot air at 300° C. to 1000° C. is supplied to the hot-blast furnace chamber, so that the atomized spherical liquid drops and hot air generate pyrolysis effect to pyrolyze the acid radicals, and the spherical liquid drops are dried instantaneously to form the spherical precursor containing lithium ions.
