Abstract
An anode protector of a lithium-ion battery and a method for fabricating the same are provided. A passivation protector (110) is formed on a surface of an anode (102) in advance by film deposition, such as atomic layer deposition (ALD). The passivation protector (110) is composed of a metal oxide having three dimensional structures, such as columnar structures. Accordingly, the present invention is provided with effective protection of the anode electrode structure and maintenance of battery cycle life under high-temperature operation.
