Advanced Functional Materials, EarlyView.Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...

Phase Diagrams Enable Solid‐State Battery Design
Advanced Materials Interfaces, EarlyView.Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but
