Reconstructing Residual‐Solvent‐Involved Li+ Coordination in PVDF‐HFP Polymer Electrolytes for Stable Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
2,2,2‐trifluoroethanamide‐mediated coordination regulation reconstructs the local Li+ environment in PVDF‐HFP polymer electrolytes by weakening residual DMF‐dominated coordination and promoting TFSI−‐involved anion‐rich solvation. This strategy facilitates Li+ migration and interfacial desolvation, promotes the formation of a thin inorganic‐rich SEI ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges
