| materials | Celgard 2325 (separator); Cu (working_electrode, current_collector); LP40 (electrolyte); Li (anode, counter_electrode); LiFSI DME (electrolyte); LiFSI DME/TTE LHCE (electrolyte) |
| nmr experiment | 1D 7Li-NMR (solution, wash-solvent quantification) |
| nmr experiment source | SI, NMR, p.18 |
| notes | Quantifies soluble SEI Li+ lost to the wash solvent. cyc_num_metadata.csv row 261_01: electrolyte=fsidme (LiFSI DME), cyc=6 (matches SI's '6 cycles for LiFSI DME' target), CE=93.62%, total capacity loss=0.7698 mAh. icp_Li and recovery_frac are blank in that row (not measured/recorded for this cell). Field strength (Larmor frequency of 7Li specifically) is left out — the SI only states the magnet's 1H frequency (500.34 MHz), not the 7Li observe frequency, and computing one from the gyromagnetic ratio would be an inferred, not a stated, number. |
