Synergistic Organic–Inorganic Interface Engineering for Stable Zinc Metal Anodes in Aqueous Batteries

open access: yesAdvanced Science, EarlyView.
A multifunctional mercaptosuccinic acid enables an ultrathin organic–inorganic SEI (Zn‐S‐RCOOH) that synergistically regulates interfacial water and accelerates Zn2+ transport. The optimized hydrogen‐bond environment and ZnS‐guided deposition suppress dendrites, corrosion, and by‐product formation, delivering ultrastable Zn cycling and high‐performance

Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

open access: yesAdvanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Interfacial Polysulfide Confinement via Spatially Controlled Sulfonated Metal–Organic Polyhedra Coatings in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Spatially controlled sulfonated metal–organic polyhedra (SMOP) coating on sulfur‐loaded hollow carbon spheres form ultrathin, conformal interfacial barriers that selectively confine soluble polysulfides, stabilize sulfur redox, and suppress shuttle reactions.
