Unsaturated Coordination Oxygen in Zn─V─O Vacancy Clusters Enables Superb Zinc Storage Capability

Advanced Science, EarlyView.
Zn3(VO4)2 with Zn─V─O vacancy clusters was synthesized and innovatively applied as cathode material in aqueous Zn‐ion batteries. In‐situ XRD, HRTEM and ab initio molecular dynamics simulations unveil the double reaction mechanism of zinc ions. Adsorption of zinc ions on unsaturated coordination O and H+ on O in ‐VO4 contributes to the main capacity. It

Synergistic Se‐Doping and Accompanying S‐Vacancies Drive Lattice Distortion and p‐Band Modulation for Enhanced Sodium Storage in Sulfides

Advanced Science, EarlyView.
Se‐doping in sulfides facilitates the creation of S vacancies. The collaboration of Se‐doping and S vacancies not only induces lattice distortion to weaken the M─S bonds and lift the p‐band center for improved Na+ adsorption, but also increases the number of charge carriers for an improved electronic conductivity.

Highly Robust Sn‐Based MAX Anodes Constructed via Ti6C Octahedral Outer Immobilization and A‐Layer Fe Inner Anchoring for Long‐Life Lithium‐Ion Batteries

Advanced Science, EarlyView.
How can Sn‐based anodes achieve high capacity and long‐life cycling? This work unlocks the potential anode structure by confining Sn in the A layer of MAX phase with Ti6C octahedra as outer immobilization and Fe as inner anchors. The introduction of Fe dramatically strengthens the Ti–Sn bond to enhance structural integrity, modulate interfacial ...
