Abstract

Highlights

LiPF₆ integration into sodium-ion battery electrolytes strengthens solid electrolyte interphase (SEI) film and stabilizes O3 electrode surfaces, enhancing cycleability with 92.7% at 400 cycles.
Li-based SEI exhibits reduced solubility, effectively suppressing sodium-ion and electron leakage, and mitigating electrolyte decomposition on hard carbon electrode.
The formation of Li-ion pillars on O3-type electrode surfaces significantly reduces oxygen release and electrolyte degradation, resulting in improved capacity retention.

锂盐对钠离子电池界面副反应的转化作用

LiPF6集成到钠离子电池电解质中，增强了固体电解质间相（SEI）膜，稳定了O3电极表面，在400次循环中提高了92.7%的可循环性。li基SEI具有较低的溶解度，有效抑制钠离子和电子泄漏，减轻硬碳电极上电解质分解。在o3型电极表面形成的锂离子柱显著减少了氧的释放和电解质的降解，从而提高了容量保持。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
