摘要：

Mn3O4/graphite powder (Mn3O4/GhP) composite was successfully obtained utilizing an alternating voltage induced electrochemical method. It was found that Mn3O4 particles (similar to 20 nm) resulted from Mn electrodes were well dispersed on the surface of GhP. The electrochemical performances of Mn3O4/GhP material as anode for lithium-ion batteries were investigated, demonstrating high specific capacity and excellent cycling stability with a high charge-discharge capacity of 1007.4 mAh g (1) after 50 cycles at a current density of 100mA g (1).
