Abstract
Disclosed is a method of preparing a positive active material for a lithium battery. The method comprises: depositing a positive active material on an electrode on a substrate (1); and putting metal chips on a metal oxides target and performing a sputtering process, thereby depositing mixed metal-oxides on the positive active material (2). In another aspect, the method comprises: preparing an electrode active material; preparing a precursor solution including the electrode active material; and printing the precursor solution on the substrate, and evaporating a solvent at a temperature of 80-120° C.
