▎ 摘　　要

As a potential alternative cathode material, alpha-LiFeO2 suffers a realization handicap, mainly due to its poor electrical conductivity and low lithium ion diffusion rate. In this work, we have successfully synthesized alpha-LiFeO2/rGO nanocomposite through a layer by layer self-assembly modification process and annealing treatment. Due to the strong electrostatic attraction between opposite charged spices, alpha-LiFeO(2 )nanoparticles were homogeneously dispersed on the graphene sheet to form a typical interconnected conducting network which was beneficial for electronic conductivity and ionic diffusivity. In comparison to pristine alpha-LiFeO2 , the alpha-LiFeO2/rGO displayed an excellent electrochemical performance with average discharge capacities of 238.9, 187.2, 178.4, 121.8 and 99.5 mA h g(-1) at 0.1, 0.2, 0.5,1 and 2 C, respectively. Besides, the specific capacity retained 164.9 mA h g(-1) and 107.98 mA h g(-1) after 50 cycles at 0.5 C and 1 C, respectively. The remarkable progress in rate capability and cycling ability of this new nanocomposite developed a new approach to improve the electrochemical performance of alpha-LiFeO2.
