abstract = {High-throughput experiments (HTE) enable fast exploration
of advanced battery electrolytes over vast compositional
spaces. Among the multiple properties considered for optimal
electrolyte performance, the conductivity is critical. An
analytical expression for ionic transport in electrolytes,
accurate for practical compositions and operating
conditions, would accelerate the process of (i)
co-optimizing conductivity alongside other desirable
electrolyte properties, and (ii) learning fundamental
physical laws from data, which is one of the paramount goals
of scientific big-data analytics. Here, we used symbolic
regression with an HTE-acquired dataset of electrolyte
conductivity and discovered a simple, accurate, consistent
and generalizable expression. Notably, despite emerging from
a purely statistical approach, the expression reflects
functional aspects from established thermodynamic limiting
laws, indicating our model is grounded on the fundamental
physical mechanisms underpinning ionic transport. We
demonstrate the potential of using machine learning with HTE
to find accurate and physically-sound models in complex
systems without established physico-chemical theories.},
