Abstract

Highlights

The capacity fading mechanism of the conventional Na₃V₂(PO₄)₃//Na₃V₂(PO₄)₃ (NVP//NVP) cell has been investigated.
All-solid-state ferroelectric-engineered composite electrolyte could improve the electrolyte–electrode interfacial stability as well as the interfacial ion conduction of the Na-ion battery using the NVP anode.
Outstanding cyclic stability has been achieved in the all-solid-state Na-ion battery using the NVP anode, with a capacity fading rate as low as 0.005% per cycle.

全固态铁电工程复合电解质带来的超稳定钠离子电池

研究了传统 Na3V2(PO4)3//Na3V2(PO4)3（NVP//NVP）电池的容量衰减机制。全固态铁电工程复合电解质可以提高使用 NVP 负极的钠离子电池的电解质-电极界面稳定性以及界面离子传导性。使用 NVP 阳极的全固态钠离子电池实现了出色的循环稳定性，每循环容量衰减率低至 0.005%。

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.
