The　further　development　of　electrode　materials　with　both　high　capacity　and　rate　capability　is　necessary　for　meeting　the　continuing　requirement　for　increasing　high-energy　density　and　long-cycle　life　of　lithium-ion　batteries　(LIBs).　Herein,　a　cathode　material　of　LIBs,　LiFePO4/C　modified　with　high　electrical　conductivity　compound　tantalum　carbide　(TaC)　is　successfully　synthesized　by　a　hydrothermal　method.　The　co-coating　of　nano-sized　TaC　and　amorphous　carbon　layer　on　the　surface　of　LiFePO4　particles　can　facilitate　good　electrons　and　Li　ions　transfer,　leading　to　faster　electrochemical　kinetics.　As　the　cathode　material　for　LIBs,　this　composite　presents　both　excellent　electrochemical　performances　with　high　reversible　capacity　(159.0　mAh　g(-1),　0.1C)　and　improved　rate　capacity.　The　methodology　developed　in　this　paper　demonstrates　a　new　prospect　for　the　application　of　transition　metal　carbides　(TMCs)　in　the　modification　of　battery　electrode　materials.
