Superlow load of nanosized MnO on a porous carbon matrix from wood fibre with superior lithium ion storage performance

Abstract

A facile synthesis of an MnO/C nanocomposite material consisting of 5.3 wt% of MnO on the surface of porous carbon is introduced. Equally distributed nanosized MnO particles and the porous carbon matrix have fully developed a synergistic effect to achieve superior lithium ion storage performance. Using the MnO/C nanocomposite material as the anode of a Li-ion battery, a high discharge capacity of 952 mA h g⁻¹ has been obtained at a current density of 0.1 A g⁻¹ with a stable cycling performance over 100 charge–discharge cycles.
