Abstract
We report a two-step approach to synthesize nanosized LiFePO4C composite by an in situ polymerization restriction method. First step, the Fe2O3@polyaniline is fabricated with in situ polymerization method. Secondly, the as-obtained Fe2O3 coated with polyaniline is mixed with LiH2PO4, followed by carbothermal reduction process. The outer polyaniline shell coating Fe2O3 can restrict the aggregation of particles and serves as carbon-containing precursor. The studies of electrochemical performances were carried out at full cell level. The results show that the assembled pouch-typed full-cells with as-obtained LiFePO4 present excellent rate capability and cycle life.
