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 ...

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.

Enabling Moisture and Interfacial Stability in Sulfide Solid Electrolytes via a Processable Organic Coating Strategy for High‐Voltage All‐Solid‐State Batteries

Angewandte Chemie, EarlyView.
The solid electrolyte, argyrodite (Li6PS5Cl or LPSCl), “waxed” with a 25 nm coating of decanoic acid (DA; C10H19O2) is protected against hydrolysis at high relative humidity and maintains its ionic conductivity. DA–LPSCl exhibits enhanced stability at both NCM|DA–LPSCl and Li|DA–LPSCl interfaces: solid state batteries with a bare NCM85 cathode and Li ...
