Rare earths are of significant benefit to the electrochemical performance, reliability, and safety of batteries. The integration of rare earth elements into MoS anode materials holds promise for enhancing the cycling stability of batteries during charging and discharging cycles. In this work, a nanoflower-like composite of CeMoO/MoS/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 CeMoO/MoS/C composite. After being annealed at 500 °C for 2 h, the CeMoO/MoS/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 was 747.98 mAh g, 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.
稀土对电池的电化学性能、可靠性和安全性具有显著益处。将稀土元素整合到MoS负极材料中有望提高电池在充放电循环过程中的循环稳定性。在这项工作中，通过增强水热法合成了一种CeMoO/MoS/C纳米花状复合材料作为负极材料。实验结果表明，碳的掺入导致材料具有更复杂的花状结构。退火过程对CeMoO/MoS/C复合材料的形貌和晶体结构影响较小。在500℃下退火2小时后，CeMoO/MoS/C复合材料作为锂离子电池（LIBs）的负极材料表现出显著的循环稳定性。在电流密度为500 mA g时的初始放电容量为747.98 mAh g，而200次循环后的放电容量显示容量保持率为77.34%。结果证明了这种材料在储能应用中的潜力，并为相关材料的合理设计提供了一种替代方案。
