Abstract

Sb₂O₃-modified Li_1.1CoO₂ material is successfully obtained by solid state reaction. The modified phase maintains the merit of high packing density of bare Li_1.1CoO₂; on the other hand, it is proved that the addition of Sb₂O₃ during the preparation effectively removes the excess Li and associated structure defect in the material. XRD, EDAX and ICP-AES measurements all reveal that the coating layer is a solid solution of LiCo_1-xSb_xO₂. Cycling and thermal test indicates that, comparing to the bare Li_1.05CoO₂, Sb₂O₃-modified Li_1.1CoO₂ material shows improved cycleabilty as well as higher thermal stability.
