Peanut-like MnO@C core–shell composites as anode electrodes for high-performance lithium ion batteries

Peanut-like MnO@C core–shell composites with an internal carbon network (P-MnO@C) were prepared via an in situ synchronous graphitization and reduction process. These P-MnO@C composites exhibit high specific capacity and rate capability, good stability and excellent long-term cycling life for application in lithium ion batteries.
