Electrochemical performance of LiFePO4/(C+Fe2P) composite cathode material synthesized by sol-gel method
A LiFePO 4 /(C+Fe 2 P) composite cathode material was prepared by a sol-gel method using Fe(NO 3 ) 3 ·9H 2 O, LiAc·H 2 O, NH 4 H 2 PO 4 and citric acid as raw materials, and the physical properties and electrochemical performance of the composite cathode material were investigated by X-ray diffracto...
