Electrostatic Regulation of Na+ Coordination Chemistry for High-Performance All-Solid-State Sodium Batteries
Highlights
An electrostatic engineering strategy is proposed to regulate the Na+ coordinated structure by employing a fluorinated metal–organic framework as an electron-rich model.
The abundant electron-rich F sites can accelerate Na-salt disassociation while forcing anions into Na+ coordination structure though electrostatic effect to weaken the Na–O coordination, thus promoting rapid Na+ transport.
Anion-rich weak Na+ solvation structure is achieved and contributes to a highly stable inorganic-rich solid–electrolyte interphase, significantly enhances the interfacial stability toward Na anode.
Impressively, Na/Na symmetric cell delivered stable Na plating/stripping over 2500 h, and the assembled all-solid-state sodium metal batteries demonstrated stable performance of over 2000 cycles under high rate of 2 C with capacity retention nearly 100%.
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.
