摘要：
Stoichiometric high temperature LiCoO2 obtained by long annealing in oxygen was characterized by electron spin resonance and magnetization measurements. Both methods allow identifying unambiguously not only the presence of traces of cobalt oxides in the material but also paramagnetic defects in lithium cobaltite itself. We report on the presence of surface Li+-O- centers in pure LiCoO2, which has not been observed before in this material, and on the presence of Co2+ related centers in argon- and subsequent oxygen-annealed samples.
