正极材料LiMnPO4/C的离子热法制备及电化学性能
Ionothermal Synthesis of LiMnPO4/C Cathode Material and its Electrochemical Performance
摘要
Abstract
A LiMnPO4 powder was synthesized in hydroxyl ammonium ionic liquids under mild condition at low temperature and ambient pressure via an ionothermal synthesis method.The LiMnPO4/C cathode material was obtained by a subsequent heat treatment with sucrose.The products were characterized by X-ray diffraction,scanning electron microscopy,transmission electron microscopy,and galvanostatic charge/discharge method,respectively.The results reveal that the average size of the sample is 150-300 nm.The LiMnPO4/C sample obtained at 700 ℃ exhibited a superior electrochemical performance with a specific discharge capacity of 114.0 mA？h/g at 0.05 C,and the capacity remained 102.3 mA？h/g after 10 cycles.It was also indicated that the ionothermal synthesis in hy-droxyl ammonium ionic liquids could be a promising route to prepare LiMnPO4 cathode materials for lithium-ion batteries.关键词
