【 摘 要 】

A novel solution combustion synthesis of nanoscale spinel-structured Co3O4 powder was proposed in this work. The obtained material was composed of loosely arranged nanoparticles whose average diameter was about 36 nm. The as-prepared cobalt oxidepowder was also tested as the anode material for Li-ion batteries and revealed specific capacities of 1060 and 533 mAh·g−1 after100 cycles at charge–discharge current densities of 100 and 500 mA·g−1, respectively. Moreover, electrochemical measurements indicate that even though the synthesized nanomaterial possesses a low active surface area, it exhibits a relatively high specificcapacity measured at 100 mA·g−1 after 100 cycles and a quite good rate capability at current densities between 50 and5000 mA·g−1.
