Abstract: Interfaces such as those between polymers and ceramics in hybrid electrolytes are challenging to characterize by magnetic resonance:(a) Sensitivity; distinction between interface and bulk: Dynamic nuclear polarization (DNP)-enhanced NMR combined with electron paramagnetic resonance (EPR) toinvestigate electrochemically deposited lithium.(b) Interpretation: Using AlPO4 as a model system for surface structure analysis via combined magic angle spinning (MAS) NMR and density functional theory (DFT) simulations.(c) Process selectivity: 7Li exchange spectroscopy (EXSY) NMR to study ion dynamics at the polymer–ceramic interface in LLZO/PEO composites.
