Abstract
Rare earths are of significant benefit to the electrochemical performance, reliability, and safety of batteries. The integration of rare earth elements into MoS(2) anode materials holds promise for enhancing the cycling stability of batteries during charging and discharging cycles. In this work, a nanoflower-like composite of Ce(2)Mo(3)O(12)/MoS(2)/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 Ce(2)Mo(3)O(12)/MoS(2)/C composite. After being annealed at 500 °C for 2 h, the Ce(2)Mo(3)O(12)/MoS(2)/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.
