摘要

MnO@C nanocomposites are synthesized by annealing MnO microspheres treated with oleic acid as carbon source.The obtained MnO@C nanocomposites exhibit a discharge capacity of 1075 mAh/g for the initial cycle,and show the excellent cycling performance with a discharge capacity of 421 mAh/g after 100 cycles at a current density of 100 mA/g.The total specific capacity of MnO@C nanocomposites is higher than those of pure MnO microspheres in our experiments.Owing to the superior electrochemical behavior,the as-obtained MnO@C nanocomposites are potentially applied as next-generation anode material for lithium-ion batteries.
