AMIDR Validation with PyBaMM

The accuracy of the Atlung Method for Intercalant Diffusion and Resistance (AMIDR) for determining solid-state lithium diffusion was evaluated using synthetic data generated with the Single Particle Model (SPM) and Doyle–Fuller–Newman (DFN) models implemented in PyBaMM. Under SPM conditions, the AMIDR model achieved single-digit errors across a wide range of parameters but exhibited significant fitting errors at extreme parameter values. DFN simulations revealed an additional systematic underestimation of diffusion at high DNMC due to electrolyte transport, with errors approaching two orders of magnitude despite optimized cell design.
