In Situ Construction Of One-Dimensional Porous Mno@C Nanorods For Electrode Materials

Owing to cost-effectiveness, low conversion potential, and high theoretical capacity (756 mA h g(-1)), MnO has been a potential candidate for LIB anode. Herein, a facile carbon modification route to prepare MnO@C nanorods with excellent capacity and long lifespan for LIB anode is presented, using MnOOH as a precursor after being annealed in Ar/C2H2 atmosphere. Notably, MnO@C displayed a superior capacity of 451 mA h g(-1) after 300 cycles at 2 A g(-1). The discharge capacity at 5 A g(-1) was 261 mA h g(-1). We found that the improved performance of MnO@C can contribute to the porous structure and the protection of carbon shell, which are confirmed by kinetic analysis and pseudocapacitance analysis.
