Abstract Lithium‐sulfur (Li–S) batteries have heretofore raised burgeoning interest due to their cost effectiveness and high theoretical energy densities. However, the inherent porous fluffy structure of sulfur impedes path constructing high‐loading electrodes (over 5 mg cm −2 ) for practicability. Furthermore, especially in thick electrodes, challenges like retarded redox kinetics, notorious polysulfide shuttling, wanton electrode expansion seriously give rise low utilization, poor rate performance, unsatisfactory cycling stability. Constructing free‐standing architectures has been demonstrated as an effective strategy tackle aforementioned issues Li–S batteries. As emerging technique, 3D printing (3DP) shows merits rapidly fabricating precise microstructures with controllable loadings rationally organized porosity. For realm, 3DP offers optimized Li + /e − transmission well‐dispersed electrocatalysts, which achieves efficient regulation guarantees favorable performance. This review covers design principle preparation printable inks, practical applications manufacture self‐supported frameworks (such cathodes, anodes, separators) Challenges perspectives on potential future development are also outlined.

Coordinated Ionic Self-Assembly of Highly Ordered Mesoporous Pt₂Sn₂S₆ Networks for Boosted Hydrogen Evolution

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: March 5, 2025

Metal sulfide materials, endowed with ordered mesoporosity, offer ample opportunities in a variety of renewable energy applications due to the integration intrinsic functional properties and enhanced reaction kinetics. Unfortunately, mesoporous metal sulfides have rarely been reported immense synthetic difficulties by conventional self-assembly approaches. Herein, we explore compatible coordinated ionic strategy for facile synthesis highly Pt2Sn2S6 networks templated mesopores at 4.2 nm hexagonal mesophase (space group p6mm) accessible surface area. The mechanism is further investigated, revealing role cationic surfactant anionic sulfur pair balancing suitable interaction utilized ammonia ligand retard fast precipitation source effective assembly. Owing combination porosity functionality, after crystallization exhibits excellent activity (overpotential 13 mV, Tafel slope 34 mV dec-1) long-term durability over 100 h electrochemical hydrogen evolution (HER) alkaline solution. Our study provides toolbox rational compositions as advanced model platforms future versatile technologies.
