Abstract:
The electronic structure and specific features of the structure of nonstoichiometric cobaltite LixNayCoO2 (x = 0. 42, y = 0. 36) have been studied comprehensively. The calculated multiplet for the lowspin state of the Co3+ ion agrees with the experimental spectra. It has been established using X-ray absorption spectra measured in the total photoelectric effect yield and total fluorescence yield modes that the LixNayCoO2 cobaltite is stoichiometric with respect to the alkali metal near its surface and is defective inside. It has been demonstrated that the charge compensation in the case of an alkali metal deficit in LixNayCoO2 is due to holes in O 2p states. © 2011 Pleiades Publishing, Ltd.
