Sodium‐ion batteries (SIBs) as economical, high energy alternatives to lithium‐ion batteries (LIBs) have received significant attention for large‐scale energy storage in the last few years. While the efforts of developing SIBs have benefited from the knowledge learned in LIBs, thanks to the apparent proximity between Na‐ions and Li‐ions, the unique physical and chemical properties of Na‐ions also distinctly differ themselves from Li‐ions. It is expected that SIBs have drastically different electrode material structure, solvation–desolvation behavior, electrode–electrolyte interphase stabilities, ion transfer properties, and hence electrochemical performance of batteries. In this review, the authors comprehensively summarize the current understanding of the anode solid electrolyte interphase and cathode electrolyte interphase in SIBs, with an emphasis on how the tuning of the stability and ion transfer properties of interphases fundamentally determines the reversibility and efficiency of electrochemical reactions. Through these carefully screened references, the authors intend to reveal the intrinsic correlation between the properties/functionalities of the interphases and the electrochemical performance of batteries.

钠离子电池的相间

在过去的几年中，作为锂离子电池（LIB）的经济，高能替代品的钠离子电池（SIB）在大规模储能方面受到了广泛关注。尽管发展SIB的努力得益于在LIB中获得的知识，但是由于Na离子和Li离子之间的明显距离，Na离子独特的物理和化学性质也与Li离子有明显的不同。可以预期，SIB具有截然不同的电极材料结构，溶剂化-去溶剂化行为，电极-电解质的相间稳定性，离子转移特性以及因此的电池电化学性能。在这篇综述中，作者全面总结了当前对SIBs中阳极固体电解质相和阴极电解质相的了解，着重于如何调整相间的稳定性和离子转移特性，从根本上决定了电化学反应的可逆性和效率。通过这些经过仔细筛选的参考文献，作者打算揭示中间相的性质/功能与电池的电化学性能之间的内在联系。
