Abstract
Manganese oxides are promising anode materials for lithium-ion batteries due to their high specific capacities and excellent chemical stability. However, the considerable volume expansion/contraction that occurs during their charge/discharge process limits their practical application. Herein, a cube-shaped MnO@C composite was prepared by calcining the MnCO₃/C precursor, which exhibited a high reversible capacity (1254.7 mAh g⁻¹ at 0.1 A g⁻¹) and a high rate performance (605 mAh g⁻¹ at 2.0 A g⁻¹). Moreover, the MnO@C composite delivered a discharge capacity of 797.8 mAh g⁻¹ at 1.0 A g⁻¹ after 1000 cycles, with negligible capacity fading. Carbon compositing improved the electrical conductivity and structural stability. The numerous channels within the MnO secondary particles facilitated Li⁺ diffusion. This strategy can provide guidance for preparing other high-performance anode materials for lithium-ion batteries.
