  High-concentration aqueous electrolytes have shown promise as candidates for
a safer, lower-cost battery system. Ionic conductivity is a key property
required in high performing electrolytes; the Advanced Electrolyte Model (AEM)
has previously shown great accuracy in predicting ionic conductivity in
highly-concentrated non-aqueous electrolytes. This work provides extensive
experimental data for mixed and highly concentrated aqueous electrolyte
systems, rapidly generated via a robotic electrolyte testing apparatus. These
data demonstrate exceptional accuracy from AEM in predicting conductivity in
aqueous systems, with the accuracy being maintained even in highly-concentrated
and mixed-salt regimes.
