Physical Chemistry Chemical Physics, Journal Year: 2023, Volume and Issue: 25(18), P. 12650 - 12667

Published: Jan. 1, 2023

In this study, we present an overview on the use of ionic liquids (ILs) as electrolytes in sodium-ion batteries (SIBs). The development SIBs has gained traction over last few years because Na is cheaper and more abundant than Li. case, although great efforts have been devoted to finding high-capacity high cell potential materials for SIBs, electrolyte safety important factor producing competitive reliable devices. Specifically, intrinsic volatility organic solvent-based commonly used commercial systems a risk during operation batteries, thus replacing them with ILs alternative that should be considered. This family thermally stable solvents, but they suffer from poor transport properties. Herein, discuss these properties, considering neat ILs, effects cations anions, effect salt concentration. Moreover, strategies overcome limitations are highlighted. Then, recent applications mixtures containing sodium salts negative positive electrodes presented. Finally, Na-IL solid-state discussed.

Liquid-Phase Exfoliation of Arsenic Trisulfide (As₂S₃) Nanosheets and Their Use as Anodes in Potassium-Ion Batteries

ACS Nano, Journal Year: 2024, Volume and Issue: 18(31), P. 20213 - 20225

Published: July 22, 2024

Here, we demonstrate the production of 2D nanosheets arsenic disulfide (As2S3) via liquid-phase exfoliation naturally occurring mineral, orpiment. The resultant had mean lateral dimensions and thicknesses 400 10 nm, structures indistinguishable from bulk. were solution mixed with carbon nanotubes cast into nanocomposite films for use as anodes in potassium-ion batteries. These exhibited outstanding electrochemical performance, demonstrating an impressive discharge capacity 619 mAh/g at a current density 50 mA/g. Even after 1000 cycles 500 mA/g, retained 94% their capacity. Quantitative analysis rate performance yielded very low 838 mAh/g, about two-thirds theoretical As2S3 (1305 mAh/g). However, this also implied to have small solid-state diffusion coefficient (∼10–17 m2/s), somewhat limiting its potential high-rate applications.

The development of high-performance metal-ion batteries mainly focuses on searching for high-capacity anodes but neglects the volume expansion effect materials during charge/discharge process. Using first-principles calculation method, we examine efficacy bilayer BC7 as an anode material Li/Na/Mg-ion batteries. Our results illustrate a strong swelling caused by penetration Na and Mg atoms into interlayer space BC7, which is responsible large renders unsuitable Na- Mg-ion On other hand, intercalation Li structure could deliver acceptable 2D theoretical capacity 423.69 mAh/g, higher than that commonly used Li-ion
