Pulse measurements are widely used in electrochemistry to measure slow diffusive dynamics , as in Galvanostatic and Potentiostatic Intermittent Titration Techniques (GITT, PITT), for which corrections for reaction limitation at short timescales have been developed . Pulse measurements are sometimes interpreted physically by porous electrode theory (PET) simulations . Despite their widespread utilization , however, there is still inadequate understanding of how pulses affect cells. For HPPC tests in particular, the theoretical understanding of pulse dynamics in the short-time reaction-limited regime is incomplete, and no clear rationale for selecting specific states of charge and currents for the applied pulses is available. While some progress has been made with porous-electrode type modeling to simulate HPPC, as shown in Fig. with pulses from measurements similar to industry-standard HPPC , HPPC protocols have not yet been optimized to extract maximum information. Approaching experimental design with PET simulations presents significant computational challenges due to the extensive search space. Furthermore, PET-type simulations often suffer from poor identifiability of parameters inferred from experimental data , which complicates attempts to predict improved experimental design. These problems have hindered progress in the search for optimal experimental protocols .
