In Situ Reconstruction of Electrocatalysts for Lithium–Sulfur Batteries: Progress and Prospects

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

Published: May 1, 2023

Abstract The current research of Li–S batteries primarily focuses on increasing the catalytic activity electrocatalysts to inhibit polysulfide shuttling and enhance redox kinetics. However, stability is largely neglected, given premise that they are stable over extended cycles. Notably, reconstruction during electrochemical reaction process has recently been proposed. Such in situ inevitably leads varied electrocatalytic behaviors, such as sites, selectivity, activity, amounts sites. Therefore, a crucial prerequisite for design highly effective an in‐depth understanding variation active sites influence factors which not achieved fundamental summary. This review comprehensively summarizes recent advances behaviors different process, mainly including metal nitrides, oxides, selenides, fluorides, metals/alloys, sulfides. Moreover, unexplored issues major challenges chemistry summarized prospected. Based this review, new perspectives offered into true batteries.

Progress on Transition Metal Ions Dissolution Suppression Strategies in Prussian Blue Analogs for Aqueous Sodium-/Potassium-Ion Batteries

Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 16(1)

Published: Feb. 21, 2024

Aqueous sodium-ion batteries (ASIBs) and aqueous potassium-ion (APIBs) present significant potential for large-scale energy storage due to their cost-effectiveness, safety, environmental compatibility. Nonetheless, the intricate mechanisms in electrolytes place stringent requirements on host materials. Prussian blue analogs (PBAs), with open three-dimensional framework facile synthesis, stand out as leading candidates storage. However, PBAs possess a swift capacity fade limited cycle longevity, structural integrity is compromised by pronounced dissolution of transition metal (TM) ions milieu. This manuscript provides an exhaustive review recent advancements concerning ASIBs APIBs. The TM PBAs, informed attributes redox processes, are thoroughly examined. Moreover, this study delves into innovative design tactics alleviate issue ions. In conclusion, paper consolidates various strategies suppressing posits avenues prospective exploration high-safety sodium-/potassium-ion batteries.

The integration of electronic effects into complexes for the construction novel materials has not yet attracted significant attention in field energy storage. In current study, eight one-dimensional (1D) nickel-based salicylic acid (Ni-XSAs, X = pH, pMe, pMeO, mMe, pBr, pCl, pF, and pCF3 ), are prepared by ligand engineering. coordination environments Ni-XSAs explored using X-ray absorption fine structure spectroscopy. charge transfer is modulated according to difference electron-donating ability substituents, combination with frontier orbital theory. Furthermore, density functional theory used investigate effect substituent position on properties complexes. Ni-mMeSA exhibits better electrical conductivity than Ni-pMeSA. electrochemical performance as an aqueous battery cathode remarkably improved a maximum 0.30 mWh cm-2 (125 Wh kg-1 ) peak power 33.72 mW (14.03 kW ). This study provides ideas application new chemistry science.
