Recent progress and strategic perspectives of inorganic solid electrolytes: fundamentals, modifications, and applications in sodium metal batteries

Abstract

A thorough overview and strategic guideline of inorganic solid-state electrolytes, focusing on the ionic conductivity and interfacial stability, for future sodium-metal batteries.

High-rate cycling in 3D dual-doped NASICON architectures toward room-temperature sodium-metal-anode solid-state batteries

“…The ZnO coating also functions as a protective layer from further chemical reduction of NASICON that has been observed to occur when in contact with molten sodium at elevated temperatures. 27,28…”

Ultrahigh‐Rate Na/Cl2 Batteries Through Improved Electron and Ion Transport by Heteroatom‐Doped Bicontinuous‐Structured Carbon

“…[1][2][3][4][5] Rechargeable Na-ion batteries have thus been considered promising alternatives to lithium-ion batteries, attributed to the high abundance of Na (nearly 1,300 times more than that of Li) in the Earth's crust. [6][7][8][9][10][11] Over the past decade, great efforts have been made to enhance the electrochemical performance of Na-ion batteries, [12][13][14][15][16] particularly for conversion-type cathodes, including but not limited to sulfur, [17][18][19][20][21] oxygen, [22][23][24][25][26] and halogen [27][28][29][30] cathodes toward higher energy densities. In particular, emerging rechargeable Na/Cl 2 batteries exhibit an exceptionally high capacity of 1,200 mAh g À 1 (based on the mass of carbon) at a discharge voltage of � 3.5 V, [27] based on the reversible NaCl/Cl 2 redox, i.e., NaCl generated from the initial discharge process is oxidized to Cl 2 during charge, which is reduced back to NaCl during the subsequent discharge.…”

Ultrafast and ultrastable FeSe2 embedded in nitrogen-doped carbon nanofibers anode for sodium-ion half/full batteries

“…With the widespread popularity of electric vehicles and smart devices, the development of lithium-ion batteries (LIBs) as the main energy storage device has been limited because of the shortage and uneven distribution of lithium resources [1][2][3][4][5]. Among the next-generation batteries, sodium-ion batteries (SIBs) are considered as promising candidates due to the abundant natural reserves and inexpensive sodium-containing resources [6][7][8][9][10][11][12]. Even with similar electrochemical mechanisms to LIBs, the larger ionic radius and heavier atomic weight of sodium will lead to sluggish ion diffusion kinetics and drastic volume changes of SIB electrodes as compared with those of lithium [13,14].…”
