- Abstract
- The lithium ion batteries based on LiNi0.5Mn1.5O4 cathode and Li4Ti5O12 anode are prepared by controlling the cathode thickness to optimize cell balancing. The relationship between N/P ratios (0.58, 0.83 and 1.07) and electrochemical performances are investigated. The capacity, rate performance are proportional to the cathode thickness while cycle performance decrease with increasing cathode thickness. It can be explained by high cycling stability of Li4Ti5O12 anode compared to LiNi0.5Mn1.5O4 cathode. These results clearly indicate that N/P ratio affects the electrochemical performances of lithium ion batteries.
