Abstract
Disclosed is a positive electrode applied in lithium battery and method for manufacturing the same. First, a lithium alloy oxide layer is formed on a substrate. Subsequently, an additional high density and low energy plasma treatment is processed, such that the lithium alloy oxide layer has a top surface composed of uniform, dense, and inter-necked nano grains, and the in-side/bottom grains of the oxide layer remain unchanged. According to experiments, the positive electrode with such properties has higher capacity and longer cycle lifetime, thereby improving the lithium battery performance.
