摘要：To address the limited cycle stability and rate capability of manganese oxide (MnO) as an anode material in rechargeable lithium-ion batteries (LIBs), a MnO@C/RGO composite was developed. The sample was synthesized using a hydrothermal method to integrate a dual carbon structure, followed by calcination in a nitrogen atmosphere. When the sample was utilized as an anode in LIBs, the electrode demonstrated a significant reversible capacity of 1114 mA h g(-1) at a current density of 100 mA g(-1) after 100 cycles. Even at 3000 mA g(-1), excellent reversible capacity of 412 mA h g(-1) after 500 cycles was obtained, and the reversible capacity of the sample was faded by merely 3.5 % (similar to 0.007 % capacity decay per cycle). The considerable volume expansion of MnO during lithium cycling can be effectively mitigated by the combined influence of the carbon structure and RGO layers. Furthermore, the RGO layers may accelerate electron transfer rate and Li+ diffusion rate during lithiation/de-lithiation processes. In particular, the MnO@C/RGO||LiNi0.8Co0.1Mn0.1O2 full coin battery exhibits a relatively stable performance with a reversible capacity of 65 mA h g(-1) after 100 cycles at 0.5C. Thus, the direct one-step hydrothermal method is a practicable strategy to fabricate double carbon structure composites for applications in energy storage and other areas.
