Abstract

Abstract: A MnOx/carbon nanocomposite was synthesized from a novel pitch-derived amphiphilic carbonaceous material (ACM). Characterization of this nanocomposite reveals that the nanosized manganese oxide particles are uniformly embedded in a porous carbon framework. When evaluated as the anode for lithium-ion batteries (LIBs), the structural features of the nanocomposite lead to an enhanced electrochemical performance with a high reversible capacity of ~ 900 mAh g −1 at 50 mA g −1, excellent cyclic stability (620mAh g −1 at 300 mA g −1 after 500 cycles) and good rate performance (~ 320mAh g −1 at 4 A g −1 ). The desirable electrochemical properties of the nanocomposite combined with its simple hybridization method make the prepared composite a promising electrode material for high-performance LIBs.
