제목 Surface modification of cathode active materials with bi-conductive polymer
초록 As an active cathode material, the layered LiNixCoyMn1-x-yO2 materials have attracted much attention as the promising cathode materials owing to their high capacity and relatively low cost.  However, the materials become unstable when they are charged to high voltage at elevated temperature because of the dissolution of transition metal from the host structure and the decomposition of organic electrolyte at high voltage. We recently reported that polymerizable monomers with suitable oxidation potential can exert a significant influence on the cycling performances of lithium-ion batteries. Surface modification of cathode active materials with conductive polymer is easy and effective way to get better electronic conductivity and electrochemical properties. In this work, we tried to improve the cycling performance and thermal stability of LiNixCoyMn1-x-yO2 active cathode materials by surface modification.
