Abstract
The cycling performances of LiNi0.5Mn1.5O4 (LNMO) were investigated and the reasons of capacity fading were discussed. The results show that LNMO can deliver about 115 mAh g−1 at 1C at different temperatures; however, it retains only 61.57 % of its initial capacity after 130th cycles at 60 °C, which is much lower than 94.46 % of LNMO at 25 °C, and the cycling performance at 1C is better than that at 0.5C. The reason of capacity fading of LNMO at 60 °C is mainly due to the lower decomposition voltage of 4.3 V with commercial electrolyte and the larger decomposition current, of which the electrolyte decomposes and interacts with active materials to lead to the larger irreversible capacity loss. While the worse cycling performance at low rate is attributed to the longer interaction time between the electrolyte with the decomposition voltage of 4.5 V and the active materials.
