| anode material | Li metal foil (counter electrode) |
| anode material source | Researcher-confirmed labelling; SI Figure S2a, p.4 |
| cathode material | None — bare Cu foil (working electrode, no active material) |
| cathode material source | Researcher-confirmed labelling for this Li||Cu CE cell; cell schematic in SI Figure S2a, p.4 |
| cell geometry | 2032 coin cell |
| cell geometry source | SI, Electrochemical testing, p.17 |
| cell geometry verbatim | 2032-type coin cell |
| cell geometry verbatim source | SI, Electrochemical testing, p.17 |
| cell id | 204_01 |
| cell id source | Filename 204_01_1-1.csv, confirmed by cyc_num_metadata.csv row 204_01 |
| cell type | half |
| cell type source | SI, Electrochemical testing, p.17 (Cu WE vs Li CE, Figure S2a) |
| electrode area cm2 | 2.01 |
| electrode area cm2 source | Computed from SI-stated 16 mm Cu WE diameter (SI, Electrochemical testing, p.17: 'Cu foil working electrode (WE, 16 mm diameter)'); area = pi*(0.8 cm)^2. Researcher's choice — a per-cell tracking sheet (cyc_num_metadata.csv) lists Cu_d(mm)=15 for this cell, not used here. |
| electrolyte | LiFSI in DME/TTE ("LiFSI DME/TTE LHCE") |
| electrolyte source | cyc_num_metadata.csv, row 204_01 (electrolyte=lhce); exact salt concentration/ratio not stated in available SI pages |
| esra id | ESRA-CYC-0027 |
| experiment type | Cycling |
| files public | true |
| institution code | ESRA |
| materials | Celgard 2325 (separator); Cu (working_electrode, current_collector); LP40 (electrolyte); Li (anode, counter_electrode); LiFSI DME (electrolyte); LiFSI DME/TTE LHCE (electrolyte) |
| notes | Li‖Cu half-cell from a lithium-metal SEI/coulombic-efficiency quantification method study (Steinberg et al., SI nz5c01274). Crimped at 0.82 T (MTI electronic crimper). Coulombic efficiency 97.11%, total capacity loss 0.6119 mAh, ICP-quantified Li inventory loss 0.3178 mAh (from cyc_num_metadata.csv, row 204_01 — the underlying ICP file for this value, 241104_202to204.txt, is not included in this upload), recovery fraction 0.519. |
| number of cycles | 12.0 |
| number of cycles source | cyc_num_metadata.csv, row 204_01 (cyc=12); matches SI's stated target of 12 cycles for LiFSI DME/TTE LHCE, p.19 |
| pi name | Maria K. Chan |
| project | Energy Storage Research Alliance |
| protocol summary | Rested 5 h; constant-capacity galvanostatic plating at 0.5 mA/cm2 to 1 mAh/cm2; stripped to 1 V cutoff; 5 min rest between half-cycles |
| protocol summary source | SI, Electrochemical testing, p.17 |
| researcher name | Musanna Galib |
| temperature c | 25.0 |
| temperature c source | SI, Electrochemical testing, p.17 ('temperature-controlled incubator at 25°C') |
