29 Summary Challenges in Li-rich layered cathode should be overcome for commercial use. Cycle performance and voltage depression are most serious problem for cell maker. Fluorine addition on Li-rich layered cathode resulted in significant increase of capacity retention and initial efficiency. With fluorine, reduced transition metals donate more electrons during charging process, leading to less oxygen removal. Al doping was attempted to control voltage depression. The voltage depression was clearly suppressed after Al doping. The analysis of exact position of dopant in host lattice is under way. For commercial use, significant efforts should be made to improve electrochemical properties p of Li-rich layered oxide. 29 /29
