英文摘要	Co3O4@nanofibers (NFs) and Co3O4@carbon NFs (CNFs) were synthesized by sol-gel electrospinning followed by annealing in air and Ar atmosphere, respectively. Co3O4@NFs and Co3O4@CNFs deliver stable cyclic performance with Li storage capacity of 330 and 400mAh/g after 170 and 200 cycles, respectively. Co3O4@CNFs deliver higher Li storage capacity more than Co3O4@NFs at each current densities in rate performance. More importantly, Co3O4@CNFs demonstrated relatively smaller internal resistance result from the comparison of electrochemical independence spectrum. Further morphology observation of the cycled electrodes indicates that the one-dimensioncal nanostrucutre of the Co3O4@CNFs is still maintaned after reacting with Li+, which is singnicicant to the electrochemical cyclic performance. This study indicates the internal resistance can be decreased by increasing electronical conductivity through electrospinning carbon coating layer, resulting in an enhanced energy storage performance.
