Three dimensional (3D) nano-LiMn0.6Fe0.4PO4@C/CNT composite was successfully synthesized by an oleylamine-assisted solvothermal method.The prepared composite showed excellent electrochemical performance,especially superior high rate capability.It could deliver a specific discharge capacity of 103.1 mAh/g,even at 80 C.The superior high rate performance of the as-prepared LiMn0.6Fe0.4PO4@C/CNT electrode is attributed to its unique 3D conducting network:(1) the prepared LiMn0.6Fe0.4PO4@C active particles were in nano-scale with a size of 30-50 nm;(2) LiMn0.6Fe0.4PO4 nanoparticles were uniformly coated by amorphous carbon with a thickness of 3 nm;(3) the graphitized conductive CNTs were dispersed homogenously among the LiMn0.6Fe0.4PO4@C active particles.The synergistic effect of the nanoscale amorphous carbon coated LiMn0.6Fe0.4PO4@C active particles and the graphitized CNTs reduces the diffusion path of the lithium ions and benefits the transference ability of electron.
