제목 Synthesis of LiNi0.5Mn1.5O4 via carbon combustion method and its application in high power LiNi0.5Mn1.5O4/Li4Ti5O12 for lithium ion battery
초록 We investigated the electrochemical performance of the spinel compound LiNi0.5Mn1.5O4 and Li4Ti5O12. LiNi0.5Mn1.5O4 synthesized by carbon combustion method as a cathode material. We used a commercial product Li4Ti5O12 as an anode material in this work. The electrolyte was 1.15 M of LiPF6 in EC-EMC-DMC (3:3:4). The LiNi0.5Mn1.5O4 / Li4Ti5O12 full cells were designed to obtain negative-to-positive (N/P) capacity ratios. The thicknesses and loading densities of the positive and negative electrodes depended on the mass ratio of electrodes. The ratio was about 2:3. The assembled full-cell of LiNi0.5Mn1.5O4 / Li4Ti5O12 exhibited good cycling performance between 1.5 V and 3.2 V. The capacity retentions were 85 % after 50 cycles.
