Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

Angewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.

Silicon‐Based Anodes for Sulfide Solid‐State Batteries: Failure Mechanisms and Multiscale Design Strategies

Advanced Energy Materials, EarlyView.
Silicon anodes in sulfide SSBs face coupled electrochemo‐mechanical failure by interface instability. This review examined recent advances and proposed mitigation strategies via material‐, electrode/interface‐, and cell‐level‐ engineering. We further evaluate scalable synthesis of sulfide SEs.

Molecular Design Strategies for High‐Voltage Organic Cathodes

Advanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

Synergistic Regulation of Interfacial Potential and Anionic Covalency for High‐Voltage Cobalt‐Free All‐Solid‐State Batteries

Angewandte Chemie, EarlyView.
A synergistic interface regulation strategy using high‐dielectric BaTiO3 and sulfate‐derived S─O bonds is developed to unlock high‐voltage LiNi0.5Mn1.5O4 all‐solid‐state batteries. By mitigating space‐charge layer effects and stabilizing lattice oxygen, the system achieves high‐rate (3 C) and durable operation in 5 V‐class cobalt‐free solid‐state ...

Improving reaction uniformity of high‐loading lithium‐sulfur pouch batteries

Carbon Energy
Lithium‐sulfur batteries (LSBs) have garnered attention from both academia and industry because they can achieve high energy densities (>400 Wh kg–1), which are difficult to achieve in commercially available lithium‐ion batteries.

Mechanisms of Alkali Ionic Transport in Amorphous Oxyhalides Solid State Conductors

Advanced Energy Materials, EarlyView.
Large‐scale machine learning‐based molecular dynamics simulations are used to investigate isovalent amorphous oxyhalides, revealing a remarkable chemically independent ionic conductivity. A rigorous analysis of alkali residence times across different metal–anion environments identifies divalent anions as key diffusion bottlenecks.
