Abstract

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