Zusammenfassung: 
The layered compound LiCoO2 was studied by means of X-ray emission (CoL alpha, OK alpha spectra) and X-ray photoelectron spectroscopy. The data were compared with those of CoO. Strong covalency of LiCoO2 was found and its value was estimated. The measurements show that LiCoO2 must be determined as a charge-transfer insulator where the band gap is formed by d(6) (L) under bar-states. Copyright (C) 1996 Elsevier Science Ltd
