Synthesis and Electrochemical Performance of Plate-like Structure LiMn0.8Fe0.2PO4/C as a Cathode Material for Lithium Ion Battery

Olivine plate-like structure LiMn 0.8 Fe 0.2 PO 4 /C has been successfully synthesized under mild conditions using H 2 O/DMSO as solvent and CTAB as surfactant.DMSO and CTAB promote the formation of plate-like structure.The prepared plate-like structure LiMn 0.8 Fe 0.2 PO 4 /C delivers a reversible capacity of 141mAh•g -1 at 0.1C-rate, with 80.2% capacity retention at 7C-rate.Meanwhile, the plate-like structure LiMn 0.8 Fe 0.2 PO 4 /C exhibits excellent cycling stability at room temperature with 98.8% capacity retention after 60 cycles at 1C-rate.The plate-like structure LiMn 0.8 Fe 0.2 PO 4 /C cathode materials may have a promising potential application in li-ion batteries.
