| EIS-derived ionic conductivity at −20 °C | Values across 48 formulations ranged from near zero to approximately 2.5 mS cm⁻¹; values above 1.0 mS cm⁻¹ occurred for samples with higher ZnSO₄ or EG content, while samples with higher DMSO or water content showed near-zero conductivity |

| LSV-derived electrochemical stability window at 20 °C | Values across 48 formulations ranged from 1.6 to approximately 5 V |
| Sample 23, 2 M ZnSO₄ in DMSO:H₂O, molar ratio 1:52.5:11.75 | Electrochemical stability window 5.2 V; ionic conductivity below 0.1 mS cm⁻¹ |
| Component correlations | ZnSO₄ correlated positively with ionic conductivity and negatively with the electrochemical stability window; DMSO correlated positively with the stability window and negatively with ionic conductivity; ethylene glycol and water showed weaker effects |
