Formation‐Stage Interfacial Regulation of δ‐MnO2 Enables Stable and Reversible Aqueous Zn‐Ion Storage

open access: yesAdvanced Science, EarlyView.
Precursor‐embedded Fe regulates the nucleation and growth of δ‐MnO2, enabling a more accessible and stable Zn‐storage interface with accelerated kinetics and suppressed Mn dissolution, while preserving the intrinsic Mn redox chemistry. ABSTRACT Layered δ‐MnO2 is a promising cathode for aqueous zinc‐ion batteries, yet its practical application remains ...

Interfacial and Hydration‐Associated Lithium Retention During FePO4 Regeneration from Spent LiFePO4 Cathodes

open access: yesAdvanced Science, EarlyView.
During iron phosphate regeneration, sequential washing distinguishes lithium fractions by accessibility: approximately 70% of precipitate‐associated lithium is washing‐removable, while approximately 30% remains after three cycles. Comparisons of simulated and practical systems associate retained lithium with hydrated amorphous Fe‐O‐P environments ...

Surface‐Selective Pt Enrichment for Stabilizing Ultrathin 2D PtCu Nanosheets Toward Durable Oxygen Reduction

open access: yesAdvanced Science, EarlyView.
Ultrathin 2D alloy nanosheet catalysts could offer exceptional catalytic activity but suffer from severe structural instability. Here, a surface‐selective Pt enrichment strategy via galvanic replacement effectively stabilizes PtCu Nanosheets while preserving their ∼ 1 nm thickness and (111) facets.
