Abstract

Preparation of metal oxides coating on the surface of LiCoO₂ particles were carried out by a gas suspension spray method and examined for their electrochemical performance for the cathode materials of lithium secondary batteries. Employed coating materials in this study were Al₂O ₃, ZrO₂ and TiO₂. Metal oxide coating increased surface area and gave the better cycle performance and higher thermal stability than uncoated LiCoO₂. This is probably due to the formation of Li-M-Co-O layers, which prevent the Co dissolution from the LiCoO₂ structure. The highest capacity retention was observed for the ZrO₂ coated LiCoO₂ in our experimental range.
