Abstract:
In a method of preparing a lithium metal oxide, a preliminary lithium metal oxide is prepared. The preliminary lithium metal oxide is washed using a washing solution to remove lithium salt impurities. The washing solution includes water and an organic ligand multimer compound. The lithium metal oxide having improved structural uniformity and stability is obtained using the washing solution.
