Fabrication and electrochemical properties of LiCo1-xRuxO2 cathode materials for Li-ion battery
Özet
LiCo1-xRuxO2 (where x - 0.0-0.5) are prepared by conventional solid-state reaction technique. The effect of Ru substitutions on the structural properties and electrochemical performance of LiCoO2 cathode materials is investigated in detail. The XRD analysis shows that increasing Ru content in LiCoO2 above x = 0.1 causes formation of different phases such as Li1.4RuO3, Li2Ru0.5Co0.5O3 and RuO2 which are used in the Li-ion batteries as an electrode materials. It is found in the XRD analysis that the Ru doping causes a decrease in the crystallite size which is important for improving the battery performance. The CV analysis shows that the Ru doping till x = 0.1 can produce an improvement in the performance of the cell and the capacity retention after 50 cycle is much better than that of the cell that fabricated using the pure LiCoO2.
