Study on new surface-modification method of LiCoO2 particles

초록

In this work, new surface-modification method of LiCoO2 particles was studied. New method consist of 1)mixing between commercial LiCoO2 and coating precursors(Li-containing and noncontaining), 2)sonochemical treatment, and 3)additional heating at specific temperature and other subsidiary steps. All electrochemical testing were performed in glove box(<1ppm of H2O and O2) and the used electrolyte was 1M LiPF6 in EC and DEC.
