Tuning the phase evolution pathway of LiNi0.5Mn1.5O4 synthesis from binary intermediates to ternary intermediates with thermal regulating agent
文献摘要：
Transition metal cation ordering is essential for controlling the electrochemical performance of cubic spinel LiNi0.5Mn1.5O4 (LNMO),which is conventionally adjusted by optimizing the high temperature sin-tering and annealing procedures.In this present work,multiple characterization techniques,including 6,7Li NMR,XRD and HRTEM,have been combined to trace the phase transformation and morphology evo-lution during synthesis.It has been illustrated that simultaneous formation of LiMn2O4 (LMO) and LiNiO2(LNO) binary oxides and their conversion into highly reactive LixNi3+yMn3.5+zO ternary intermediate is a thermal dynamically difficult but crucial step in the synthesis of LNMO ternary oxide.A new strategy of modifying the intermediates formation pathway from binary mode to ternary mode using thermal reg-ulating agent has been adopted.LNMO synthesized with thermal regulating agent exhibits supreme rate capability,long-cycling performance (even at elevated temperature) and excellent capacity efficiency.At a high rate of 100 C,the assembled battery delivers a discharge capacity of 99 mAh g-1.This study pro-vides a way to control the formation pathway of complex oxides using thermal regulating agent.
