The high capacity cathode materials with charge voltage above 4.5 V are widely being developed. To reduce surface reactivity at high voltage, Al 2 O 3 and pullulan are used for coating on the Li(Li 0.08 Ni 0.34 Co 0.08 Mn 0.5 )O 2 surface and are characterized by electrochemical analysis. Charge/discharge and electrochemical results reveal that the organic coating sustains in high voltage cycles. Ionic conductivity of surface coating plays a key role in the battery performance.
