Systems and methods described herein relate to assessing the quality of electrocatalyst-loaded disk electrodes. In one embodiment, a system that assesses the quality of electrocatalyst-loaded disk electrodes receives one or more images of a disk electrode on which an electrocatalyst has been deposited to produce an electrocatalyst-loaded disk electrode. The system also processes the one or more images using a machine-learning-based model trained to generate a prediction of a Koutecky-Levich (K-L) quality assessment of the electrocatalyst-loaded disk electrode. The system also accepts or reject inclusion of the electrocatalyst-loaded disk electrode in an electrochemical experimentation process based, at least in part, on the prediction.
