Multiple Operando Fields Can Identify a Predictive Mass Transport Theory in Electrolytes

The Journal of Physical Chemistry C, Journal Year: 2025, Volume and Issue: 129(6), P. 2874 - 2882

Published: Jan. 31, 2025

An electrolyte transport theory connects its properties, evolution of spatiotemporal fields (e.g., concentration), and corresponding macroscopic current voltage responses. Given this interconnection, the properties are typically inferred by analyzing response through lens a chosen theory. Unfortunately, same measurements can be analyzed using different theories to arrive at seemingly dissimilar that inconsistent with each other. We offer resolution dilemma multiple (i.e., operando) for given electrolyte. show predictive analyze operando estimate underlying subsequently predict another field. A passing test identifies meaningful such behavior accurately predicted over wide range excitations, is critical property-based screening discovery efforts.
