A Battery capacitor was prepared by controlling the mixing ratio of positive materials of the positive electrode to optimize cellproperties. The positive electrode was made by mixing two types of LiNi0.6Mn0.6Co0.2O2 (NMC 622) and LiCoO2 (LCO), andthe electrode was fabricated by changing the ratio of the two positive materials. Increasing of the content of LCO, decreasedthe capacity, and the retention of discharge capacity as a function of current rates did not change remarkably with anincreasing of the content LCO on the mixing ratio of positive materials. The life characteristics showed the highest capacityretention rate compared to the initial period under the condition that the ratio of NCM and LCO was 66 to 20. These resultsclearly indicate that mixing ratio of positive materials affects the electrochemical performances of battery capacitor.
