In view of these challenges, we choose to tackle this problem from a physics-based per- spective by finding a physical interpretation of cell behavior subject to pulsed conditions, and attempt to find a comprehensive method to understand pulse experiments. Since the most common protocols in a battery cell are galvanostatic or potentiostatic control, we aim to unravel dynamics within the cell during these conditions, leveraging mathematical analysis to extract information. Because degradation mechanisms are convoluted between the two electrodes, distinguishing physical degradation mechanisms for a full cell is not simple. To address this challenge, we develop a comprehensive theoretical framework and separate mechanisms for a half-cell material, then expand the framework to a full cell and validate with results from porous electrode simulations. Our investigations have led to the development of an explicit representation that separates degradation mechanisms for full cells.
