Ammonium Ion Batteries: Material, Electrochemistry and Strategy

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(23)

Published: March 8, 2023

Abstract Ammonium‐ion batteries (AIBs) have recently attracted increasing attention in the field of aqueous owing to their high safety and fast diffusion kinetics. The NH 4 + storage mechanism is quite different from that spherical metal ions (e.g. Li , Na K Mg 2+ Zn ) because formation hydrogen bonds between host materials. Although many materials been proposed as electrode for AIBs, performances hardly meet requirement future electrochemical energy devices. It thus urgent design exploit advanced AIBs. This review highlights state‐of‐the‐art research on insights into basic configuration, operating recent progress corresponding electrolytes AIBs comprehensively outlined. are classified compared according behaviour structure. challenges, strategies perspectives also discussed development

Sulfur–Carbon Electrode with PEO‐LiFSI‐PVDF Composite Coating for High‐Rate and Long‐Life Lithium–Sulfur Batteries

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(36)

Published: Aug. 9, 2023

Abstract To address the problem of serious capacity fading in lithium–sulfur batteries, a multi‐functional PEO(polyethylene oxide)/LiFSI (lithium bis(fluorosulfonyl)imide)/PVDF (polyvinylidene fluoride) (PLP) gel polymer electrolyte is exploited by coating PLP on carbon nanotubes (CNTs) based sulfur cathode (PLP‐S/CNTs) with controlled thermal annealing process. The process leads to conformal infusion through matrix S/CNTs retaining amorphous phase PLP, which enhance rate performance compared bare S/CNTs. drives transformation more elemental Li 2 S /Li without forming intermediary product restraining soluble‐polysulfides formation. Furthermore, successfully inhibits dissolution x ( > 4) PEO and prevents loss active material cathode, confirmed density functional theory calculations. Comprehensively, applied surface exhibit significantly suppressed shuttle effect greatly improve long‐term cycle stability battery. synthesized PLP‐coated composite demonstrates high specific 573.6 mAh g −1 at current 0.5 C after 1 000 cycles, even achieving 318.1 an extremely C‐rate (6 C). unprecedented among reported studies technology.

Cellulose‐based Interfacial Solar Evaporators: Structural Regulation and Performance Manipulation

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(36)

Published: May 15, 2023

Abstract The shortage of freshwater resources has become a major obstacle threatening human development, and directly utilizing solar energy by evaporators is emerging as promising method to produce from the seawater. Compared many synthetic polymer‐based evaporators, cellulose‐based are expected offer more interesting features benefiting renewable feature abundant reserves cellulose‐contained naturally occurring materials. First, according different fabrication methods, can be divided into two types, i.e., top‐down utilization (wood‐based) bottom‐up assembled (cellulose composite‐based), respectively. schemes also bring their own unique advantages, such bimodal porous structure wood‐based artificial interconnection microporous network cellulose composite‐based evaporators. Subsequently, this review further summarizes most recent advances highlights those focusing on structural regulation strategies (e.g., drilled channel array, asymmetric wettability structure, delignification, 2D waterway, etc.) evaporation performance improvements salt resistance, high rate, etc.). Finally, challenges in field potential solutions discussed, which anticipated provide new opportunities toward future development other kinds biomass‐based
