Sodium-ion batteries (SIBs) is a promising alternative for lithium-ion batteries (LIBs) due to abundant resources and low cost. Herein, a series of composites, CDC/SbSxx (xx means weight content of Sb2S3), composed from catkin derived carbon (CDC) material, possessing tube-like morphology, and Sb2S3 fine particles prepared by solvothermal method were selected as anodes for SIBs. The electrochemical property results demonstrated that the CDC/SbSxx electrodes afforded improved cycling stability and enhanced rate performance due to the higher Sb2S3 particle retention ability and improved electric conductivity. Furthermore, the content of Sb2S3 played in important role in electrochemical performance. The CDC/SbS15 composite electrode accommodated a higher Sb2S3 content (16.8 wt%) and exhibited improved discharge capacity and excellent cycling performance even at a high current density. Given the cost effectiveness and material sustainability, this work provides a potential strategy to develop low-cost and sustainable composite anode for advanced SIBs.

生物质碳结合不同含量的硫化锑作为负极提高钠离子电池的循环稳定性

由于资源丰富且成本低,钠离子电池(SIB)是锂离子电池(LIB)的有前途的替代品。在此,一系列复合材料 CDC/SbSxx(xx 表示 Sb 2 S 3的重量含量)由柔荑花衍生碳(CDC)材料组成,具有管状形态,并通过溶剂热法制备Sb 2 S 3细颗粒。被选为 SIB 的阳极。电化学性能结果表明,CDC/SbSxx 电极由于更高的 Sb 2 S 3颗粒保留能力和改善的电导率而提供改善的循环稳定性和增强的倍率性能。此外,Sb 2 S 3的含量对电化学性能起着重要作用。CDC/SbS15 复合电极具有更高的 Sb 2 S 3含量(16.8 wt%),即使在高电流密度下也表现出更高的放电容量和出色的循环性能。鉴于成本效益和材料可持续性,这项工作为开发用于高级 SIB 的低成本和可持续复合阳极提供了一种潜在的策略。
