Ether‐Based Electrolytes and the Solvation Structure in Sodium Ion Batteries

Advanced Energy Materials, EarlyView.
Ether electrolytes enable high‐performance sodium‐ion batteries through their unique physicochemical properties, particularly distinctive solvation structures and co‐intercalation behavior. However, the localized solvation structure and its dynamic evolution during electrochemical processes remain a “black box”.

Fluorination-Induced Conversion of the Quasi- to the Normal Interchain Packing in Push–Pull Conjugated Polymer Aggregates

We investigated the chain-length and fluorination effects on photophysics within push–pull conjugated polymer (CP, Mw 40k/100k PBDB-T and Mw 100k PM6) aggregates using transient absorption spectroscopy.

Pt Single‐Atom Catalysts on FTO for Optically Invisible pH‐Universal Hydrogen Evolution Electrodes

Advanced Energy Materials, EarlyView.
Comparison of the overpotential (η) at 10 mA cm−2 in acidic electrolyte of Pt SA on FTO (this work) and other literature. ABSTRACT Transparent hydrogen‐evolution electrodes are essential for photoelectrochemical and optoelectronic energy‐conversion devices, yet typically suffer from a trade‐off between catalytic activity and optical transmission. Here,

Directional Second Sphere Effect on CO2 Activation and Reduction by Iron Porphyrin in Aprotic and Protic Media

Angewandte Chemie, EarlyView.
Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Internal Electric Field‐Guided, Low‐Adsorption Ferroelectric Anode Protective Layers for Sustainable Suppression of Polysulfide Side Reactions in Lithium–Sulfur Batteries

Advanced Energy Materials, EarlyView.
A positively polarized ferroelectric β‐pvdf layer incorporating fluorinated boron nitride nanosheets (PPFBN) establishes a strong internal field that promotes Li+ transport toward the anode while suppressing the migration of polysulfide anions. In addition, its intrinsically low polysulfide affinity helps preserve protective‐layer functionality ...

Local Acidity as a Corrosiveness Descriptor of Fluorinated Ether Solvents in Lithium–Metal Batteries

Angewandte Chemie, EarlyView.
Adjusting the extent of solvent fluorination reveals a trade‐off between the solvation power and solvent acidity of electrolytes for lithium–metal batteries (LMBs). F4MEP is within the optimal window and balances anion‐rich solvation with suppressed Li corrosion for stable interphase formation to extend the cycle life of LMBs.

Surface‐Strained NiMo Cathodes Enable Kinetics‐Decoupled Hydrogen Bubble Management for Stable Near‐Neutral Water Electrolysis

Advanced Energy Materials, EarlyView.
Surface strain tunes the NiMo/electrolyte interface without altering intrinsic hydrogen evolution reaction (HER) kinetics. The strained surface exhibits a lower effective bubble‐detachment tendency and faster release of smaller H2 bubbles, sustaining a more accessible catalytic interface in near‐neutral electrolyte. Reduced bubble‐induced transport and
