Abstract
The perovskite-type composite metal oxide LaCoO3 was firstly used as an electrode material in rechargeable lithium cells. X-ray diffraction (XRD), scanning electron microscopy (SEM) and extended X-ray absorption fine structure (EXAFS) were employed to analyze the structures of synthesized and discharged LaCoO3 samples. Cyclic voltammetry and galvanostatic cell cycling were used to characterize the electrochemical performance of LaCoO3/Li cells. A stable reversible capacity from 110 to 130 mAh/g during up to 50 cycles can be achieved. Based on the analyses of ex-situ XRD and EXAFS of the lithiated/delithiated LaCoO3 electrode, a three-step electrochemical reaction mechanism was proposed.
