Abstract

Change in electronic structure by lithium ion deintercalation in LiNiO2 was investigated by Ni L-edge and O K-edge X-ray absorption near edge structure (XANES). The Ni Ledge XANES for LiNiO2 indicated the Ni occurs in LiNiO2as Ni2+ ions. The Ni L-edge XANES: for LixNiO2 showed no chemical shift toindicate that the Ni ion in LixNiO2 is still Ni2+, even at low x value. The O K-edge XANES for LixNiO2 also indicated that the holes compensating thelithium ion deintercalation are located primarily in oxygen 2p states rather than in Ni 3d states.
