Abstract

Developing a robust cathode-electrolyte interface (CEI) is crucial for stable layered cathode in sodium-ion batteries (SIBs). A CEI based on ester electrolytes often exhibit poor stability and robustness, which cannot address the issues of structural collapse and material dissolution in layered cathodes. However, there are few reports on constructing a stable CEI for layered cathode based on ether electrolytes. Here we develop a robust CEI for O3-type cathode via DME solvent, which enables a long-term stability of full SIBs. The results indicate that unique decomposition process of DME yields favorable organic component (e.g. RCH2ONa) and high content of inorganic components (e.g. NaF and Na2CO3) in the CEI, which is quite different from ester electrolyte, improving Na+ diffusion kinetic and interfacial stability. Notably, the O3-NaNi0.5Mn0.5O2||Na cell with the designed electrolyte demonstrates outstanding stability up to 500 cycles. Furthermore, the full cell exhibits remarkable cycling performance with a capacity retention of 85% over 200 cycles. This work provides an opportunity for stable operation of layered cathode materials via inexpensive ether electrolytes.

实现稳定的醚基钠离子全电池的 O3 型层状阴极的稳健界面
开发稳健的阴极-电解质界面(CEI)对于钠离子电池(SIB)中稳定的层状阴极至关重要。基于酯类电解质的阴极-电解质界面通常表现出较低的稳定性和鲁棒性,无法解决层状阴极中的结构坍塌和材料溶解问题。然而,关于基于醚电解质构建稳定的层状阴极 CEI 的报道却很少。在此,我们通过二甲醚溶剂为 O3 型阴极开发了一种稳健的 CEI,从而实现了全 SIB 的长期稳定性。结果表明,二甲醚的独特分解过程在 CEI 中产生了有利的有机成分(如 RCH2ONa)和高含量的无机成分(如 NaF 和 Na2CO3),这与酯类电解质截然不同,从而改善了 Na+ 扩散动力学和界面稳定性。值得注意的是,使用所设计电解质的 O3-NaNi0.5Mn0.5O2||Na 电池在 500 个循环周期内表现出卓越的稳定性。此外,整个电池在 200 次循环中的容量保持率达到了 85%,显示出卓越的循环性能。这项研究为通过廉价的醚电解质实现层状阴极材料的稳定运行提供了机会。
