摘要
镁离子电池因其体积容量高、资源丰富、环境友好等优势,在大规模储能领域有着重要的应用前景。然而,由于镁离子较高的电荷密度和较强的溶剂化作用限制了其在电极和电解质中的可逆脱嵌,导致其电化学性能不佳。因此,开发稳定、高效的电极材料,同时设计并优化与其相匹配的电解质对于构建高容量、长寿命的镁离子电池至关重要。主要总结了镁离子电池电极材料和电解质最新的研究进展,讨论了它们面临的挑战和可行的解决策略,为今后的研究提供参考。
Rechargeable magnesium-ions batteries(RMBs)have attracted termendous attention in large-scale energy storage applications due to the high volumetric capacity,great earth abundance,and environmental friendliness.However,the existing electrodes and electrolyte cannot fully facilitate the Mg2+ion insertion/extraction due to the higher charge density and stronger solvation of Mg ions,resulting in a poor electrochemical performance.Developing stable and high-efficiency electrode materials is thus a key issue to promote the practical application of RMBs.Furthermore,it is essential for the construction of high-capacity and long-lifespan RMBs to optimize the electrolyte.Recent development on electrode materials and electrolytes for RMBs was reviewed,and some challenges and possible resolution strategies were also discussed.
