Hydrothermal Synthesis and Electrochemical Performance of the Ce₂Mo₃O₁₂/MoS₂/C Composite as Anode Material for Lithium-Ion Batteries

Rare earths are of significant benefit to the electrochemical performance, reliability, and safety of batteries. The integration of rare earth elements into MoS₂ anode materials holds promise for enhancing the cycling stability of batteries during charging and discharging cycles. In this work, a nanoflower-like composite of Ce₂Mo₃O₁₂/MoS₂/C was synthesized as an anode material by an enhanced hydrothermal method. The experimental results showed that the incorporation of carbon resulted in a more sophisticated flower-like structure of the material. The annealing process has little effect on the morphology and crystal structure of the Ce₂Mo₃O₁₂/MoS₂/C composite. After being annealed at 500 °C for 2 h, the Ce₂Mo₃O₁₂/MoS₂/C composite exhibited remarkable cycling stability as an anode material for lithium-ion batteries (LIBs). The initial discharge capacity at a current density of 500 mA g^-1 was 747.98 mAh g^-1, while the discharge capacity after 200 cycles exhibited a capacity retention rate of 77.34%. The results demonstrate the potential of this material for energy storage applications and provide an alternative to the rational design of related materials.
