摘要
锂矿资源不断消耗和分布不均等问题日益突出,严重阻碍了锂离子电池(LIBs)在未来市场中的应用。由于钠离子电池(SIBs)和钾离子电池(PIBs)具有储量丰富、成本低廉和环境友好等特点,有望在部分领域替代LIBs。考虑到K/K+的氧化还原电位比Na/Na+低,PIBs在输出功率和容量方面可能比SIBs更具竞争性。因此,不久的将来二次能源市场可能会大力发展PIBs。锡(Sn)基材料由于在LIBs和SIBs中具有较高的理论容量和较低的成本,得到了大量研究,然而其在PIBs中的研究处于起步阶段。为助力Sn基材料在PIBs中得到商业化应用,从材料合成、结构设计和性能优化的角度,详细阐述了现阶段Sn基材料在PIBs中的重要成果。在此基础上,探讨了Sn基材料面临的挑战和未来的发展方向并提出了改进建议,以期为Sn基材料的技术进步提供新的思路。
In recent years,the issues such as the continuous consumption and uneven distribution of lithium ore resources have become increasingly prominent,seriously hindering the application of lithium-ion batteries(LIBs)in the future market.Sodium-ion batteries(SIBs)and potassium-ion batteries(PIBs)are expected to replace LIBs in some fields due to their abundant reserves,low cost and environmental friendliness.Considering that the oxidation reduction potential of K/K+is lower than that of Na/Na+,PIBs may be more competitive than SIBs in terms of output power and capacity.Therefore,the secondary energy market may vigorously develop PIBs in the near future.Tin(Sn)-based materials have received extensive research due to their high theoretical capacity and low cost in LIBs and SIBs.However,their research in PIBs is still in early stages.To assist in the commercial application of Sn-based materials in PIBs,this article elaborates on the important achievements of Sn-based materials in PIBs from the perspectives of material synthesis,structural design and performance optimization.On this basis,the challenges faced by Sn-based materials and the future development directions are explored,and some suggestions for improvement are proposed,so as to provide new ideas for the technological progress of Sn-based materials.
