Particle‐Level ZrO2 Atomic Layer Deposition Enables Fast‐Cycling and Long‐Life Graphite Cathodes for Dual‐Ion Batteries

Advanced Functional Materials, EarlyView.
A spatial location of atomic layer deposition (ALD)‐derived ZrO2 coatings is demonstrated to be a critical design parameter for stabilizing graphite cathodes in DIBs. Direct particle‐level ALD (PALD) screening of representative metal oxides identified ZrO2 as the coating that provides the most favorable balance of high‐rate capability and interfacial ...

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride

Advanced Functional Materials, EarlyView.
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.
