摘要：

Cobalt L-edge and oxygen K-edge X-ray Absorption Near Edge Structure (XANES) investigated change in electronic structure by electrochemical lithium ion de-intercalation in LiCoO2. The Co L-edge XANES of Li1-xCoO2 did not show any chemical shift even at high x value. The oxygen K-edge XANES of Li1-xCoO2 indicated that the holes compensating the lithium ion deintercalation are located primarily in the oxygen 2p states rather than in the Co 3d states.
