Electrochemically Alternating Voltage Induced Mn3O4/Graphite Powder Composite with Enhanced Electrochemical Performances for Lithium-ion Batteries

Mn3O4/graphite powder (Mn3O4/GhP) composite was successfully obtained utilizing an alternating voltage induced electrochemical method. It was found that Mn3O4 particles (∼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 100 mA g−1.
