Abstract
Cobalt L-edge and oxygen K-edge X-ray Absorption Near Edge Structure (XANES ) investigated change in electronic structure by electrochemical lithium io n 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-xC oO2 indicated that the holes compensating the lithium ion deintercalation a re located primarily in the oxygen 2p states rather than in the Co 3d state s.
