The demand for energy storage devices has increased significantly, and the sustainable development of lithium-ion batteries is limited by scarce lithium resources. Therefore, alternative sodium-ion batteries which are rich in resource may become more competitive in the future market. In this work, we synthesized low-cost SnS/C and FeS/C anode materials of sodium-ion batteries which used waste crab shells as biomass carbon precursor. The SnS nanosheet and FeS nanosphere structures are deposited on the crab shell-derived carbon through simple hydrothermal reaction. Due to the coexistence of transition metal dichalcogenides (TMDs) and crab-derived biomass carbon, the anode material has excellent cycle stability and rate performance. SnS/C and FeS/C deliver capacities of 535.4 and 479 mA h g at the current density of 0.1 A g, respectively. This study explored an effective and economical strategy to use biomass and TMDs to construct high-performance sodium-ion batteries.
对储能设备的需求显著增加，而锂离子电池的可持续发展受到锂资源稀缺的限制。因此，资源丰富的钠离子电池在未来市场可能会更具竞争力。在这项工作中，我们以废弃蟹壳作为生物质碳前驱体，合成了低成本的钠离子电池SnS/C和FeS/C负极材料。通过简单的水热反应，将SnS纳米片和FeS纳米球结构沉积在蟹壳衍生的碳上。由于过渡金属二硫属化物（TMDs）和蟹衍生生物质碳的共存，负极材料具有优异的循环稳定性和倍率性能。在0.1 A g的电流密度下，SnS/C和FeS/C的容量分别为535.4和479 mA h g。本研究探索了一种利用生物质和TMDs构建高性能钠离子电池的有效且经济的策略。
