Lithiation‐Driven LiCrSe2 Shell Growth on Metallic CrSe2 Core Governs the Plateau–Slope Behavior

Advanced Science, EarlyView.
Layered CrSe2 is investigated as a lithium‐ion battery cathode combining fast Li+ diffusion and structural reversibility. Calculations and experiments reveal a single topotactic intercalation process with a characteristic plateau–slope profile governed by lithiation‐induced conductivity changes. A core‐shell lithiation evolution underpins its high‐rate

Engineered Interfacial Control for Suppression of Phase Instability: Operando Visualization from Device to Module Scale

Advanced Science, EarlyView.
Operando real‐time current density–voltage absorption spectroscopy visualizes spatial phase evolution in mixed‐halide perovskites from device to module scale. Phase instability preferentially initiates in regions with insufficient carrier extraction, revealing electrical boundary conditions as governing factors.

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Electric‐Field‐Driven Bilayer Interphase from Oxygenated Nanodiamond‐Carbon Nanoparticles for Dendrite‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
Electric‐field‐driven carbon migration within an oxygen‐functionalized nanodiamond/carbon composite induces the formation of a vertically graded interphase that homogenizes Li‐ion flux and suppresses dendritic nucleation. This hierarchically organized structure stabilizes the electrode–electrolyte interface and delivers durable, dendrite‐free operation
