Abstract
Provided is a method of manufacturing a high-purity lithium phosphate by utilizing a lithium waste liquid of a wasted battery. Lithium phosphate is manufactured and refined by using a minimized amount of sodium hydroxide and by using phosphate, lithium hydroxide, and an optimized pH condition, so that it is possible to manufacture high-purity lithium phosphate from which fine impurities which cannot be removed by cleaning are effective removed. A waste water treatment process of processing waste water as to be immediately discharged is integrated, so that the method is very efficient and environment-friendly. Therefore, since the high-purity lithium phosphate can be manufactured by utilizing a lithium waste liquid discarded in a wasted battery recycling process, the method has an effect in that the method is applied to a wasted battery recycling industry to prevent environmental pollution and facilitate recycling resources.
