MnO nanoparticles interdispersed in 3D porous carbon framework for high performance lithium-ion batteries

Interdispersed MnO nanoparticles that are anchored and encapsulated in a three-dimensional (3D) porous carbon framework (MnO@CF) have been constructed, which display nanosphere architecture with rich porosity, well-defined carbon framework configuration, and excellent structure stability. When evaluated as an anode material, the MnO@CF exhibits relatively high specific capacity of 939 mA h g^-1 at current rate of 0.2 A g^-1 over 200 cycles and excellent rate capability of 560.2 mA h g^-1 at 4 A g^-1. By virtue of its mechanical stability and desirable ionic/electronic conductivity, the specific design can be a promising approach to fabricate high-performance lithium-ion batteries.
