- Modification by surface coating of cathode materials is one of the preferred methods to achieve
improved electrochemical performance, especially at a high-charge cut-off voltage. In this study,
ZnO-coated LiCoO2 powders were prepared by plasma-enhanced chemical vapor deposition (PE-CVD). In
our previous work , the roles of ZnO coating in the capacity retention of LiCoO2 during high-voltage
cycling in the range of 3.0 Ve4.5 V and the thermal stability of the charged LiCoO2 electrode were
investigated as a function of the coating amount. This study confirms the positive effect of ZnO coating on
cyclic performances of LiCoO2, in particular at various C-rates and operating temperatures. In addition,
the structural stability of the LiCoO2 materials coated with different amount of ZnO during cycling was
investigated using cyclic voltammetry.
