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)
