Abstract The lithium–sulfur (Li–S) battery system has attracted considerable attention due to its ultrahigh theoretical energy density and promising applications. However, with the increasing demands on S loading electrolyte content, practical Li–S batteries still face several serious challenges, such as slow reaction kinetics at cathode interface, unstable anode interface reactions, undesirable crosstalk effects between anode. Traditional systems often struggle address these challenges under conditions, thereby rendering it imperative establish a new for batteries. This review first discusses necessity of establishing propose specific parameter requirements, electrolyte‐to‐sulfur mass ratio (E m /S). Subsequently, some modification strategies proposed by researchers are summarized different associated Finally, combination is reviewed, aiming reveal more effective design approaches that simultaneously multiple while providing guidance balanced article promotes development electrolytes can act reference other secondary

In‐situ polymerized solid/quasi‐solid polymer electrolyte for lithium‐metal batteries: recent progress and perspectives

Chemistry - A European Journal, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 11, 2024

Abstract In pursuit of high energy density, lithium metal batteries (LMBs) are undoubtedly the best choice. However, leakage and inevitable dendrite growth in liquid electrolytes seriously hinder its practical application. Solid/quasi‐solid state have emerged as an answer to solve above issues. Especially, polymer with excellent interface compatibility, flexibility, ease machining become a research hotspot for LMBs. Nevertheless, contact between electrolyte inorganic electrode materials low ionic conductivity restrict development. On account these, situ polymerized is proposed. Polymer solid produced through polymerization promote robust while simplifying preparation steps. This review summarized latest progress These were divided into three parts according their methods: thermally induced polymerization, chemical initiator ionizing radiation so on. Furthermore, we concluded major challenges future trends It's hoped that this will provide meaningful guidance on designing high‐performance

3D printing zwitter Molecule‐Enhanced Solid Polymer Electrolytes for High‐Energy Lithium Metal Batteries

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 19, 2025

Abstract Unsatisfying preparation controllability, mechanical properties, ionic conductivities, and working voltage windows limit the practical applications of solid polymer electrolytes (SPEs) in lithium‐metal batteries. Herein, a 3D printing strategy combined with zwitter molecule modification is proposed to efficiently solve problems SPEs polyvinylidene fluoride‐hexafluoropropylene (PH) matrix. The electron‐donating property resulting from carboxyl groups aspartate acid (Asp) induces cis‐conformation change fluoride, which enhances Li + transport anion immobilization on chains. In addition, amphoteric functional Asp simultaneously promote lithium salt dissociation desolvation N,N‐dimethylformamide, thus leading formation stable 3 N/LiF‐enriched interphases between electrodes electrolyte. Moreover, technology increases continuity uniformity SPE membrane, further increasing conductivity properties. As result, exhibits high (1.20 × 10 −4 S cm −1 ), large transfer number (0.68), wide electrochemical window (4.6 V), good tensile strength (≈110 MPa), endowing half cells cycling performance over 2000 h low overpotential 40 mV. Furthermore, high‐energy densities (492 Wh kg 1303 L ) are delivered by pouch cell SPE, indicating application prospects.

Contamination introduced by multilayer dielectric grating (MLDG) fabrication increases the risk of laser-induced damage when exposed to intense laser fields, consequently reducing resistance MLDGs in picosecond-petawatt systems. While considerable efforts have focused on cleaning methods minimize contamination, studies optimizing etching process remain limited. In this study, two different beam-current protocols were employed fabricating and thin films comprehensively evaluate adverse effects subsurface defects process. The results revealed that penetration fluorine contamination defects, degree increased high-beam (HBE) protocol. Furthermore, quantity typical shallow pits exhibited a significant increase HBE under 7.6 ps irradiation, 0% thresholds gratings fabricated through low-beam (LBE) protocol achieved improvements 33% 26%, respectively, compared those obtained with LBE will be meter-scale improve picosecond resistance.
