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

open access: yesAdvanced 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 ...

Effect of Microstructure and Space Charge on Cathodic Polarization

open access: yesECS Proceedings Volumes, 2005
Bar-shaped samples of porous samaria-doped ceria (SDC) with large neck sizes were fabricated using a three-step method. In the first step, two phase samples containing NiO + SDC were fabricated by sintering powder compacts. In the second step, NiO was reduced to Ni at 800°C in a hydrogen-containing atmosphere.
