主 题:vanadium oxides solvothermal microwave-assisted synthesis hollow microspheres lithium ion batteries
摘 要:In this work,hollow structured V_2O_5 microspheres were fabricated from solid vanadium precursor microspheres which were prepared by microwave-assisted,solvothermal *** the annealing process,the spherical precursor microspheres can be converted into hollow microspheres,serving as a sacrificial *** synthesis approach is quite different from the previously reported approaches for the preparation of hollow structured V_2O_*** cathode materials for lithium ion batteries,the hollow-structured V_2O_5 microspheres exhibit high capacity and good rate *** electrodes deliver specific discharge capacities of 132 and 113 mA h g^(-1) at the current densities of 1 C and 8 C,respectively.
