چکیده انگلیسی
Fe2O3/ordered mesoporous carbons (OMCs) have been synthesized by a facile one-pot hydrothermal method via self-assembly process. The combination of OMCs and anchored Fe2O3 nanoparticles shows a synergistic effect which results in a kind of anode materials with enhanced electrochemical performance for lithium ion batteries. OMCs with highly porous mesostructure and good conductivity not only alleviate the problem of volume variation and agglomeration of Fe2O3, but shorten the diffusion pathway of Li+ ions, which efficiently overcomes the problem of rapid capacity loss of iron oxide. Moreover, appropriate loading amount of Fe2O3 nanoparticles is believed to be a key factor to enhance the capacity of anode materials. The materials deliver an excellent reversible capacity of 789â¯mAhâ¯gâ1 at a current density of 100â¯mAâ¯gâ1 after 120â¯cycles.
