摘要 The chemical composition of the passivating layer formed on nano SnO2 anodes in 1 M LiClO4+ (ethylene carbonate)EC + (dimethyl carbonate)DMC at different charge/discharge states in lithium secondary batteries was studied using extra reflectance FTIR spectra. Results show that solvent decomposition reaction that generally occurs on the surface of carbon and alkali metal electrodes also takes place on nano-SnO2 anode, and the major constituent of the passivating layer is Li2CO3 and ROCO2Li. Formation of the passivating layer would certainly lead to the irreversible capacity loss.
