When the electrochemical testing machine is activated, the resulting data corresponding to the final manufactured cell is used to calculate the gravimetric cell energy density of the cell. The parameters are used in two different ways. Only certain parameters, such as chemistry, electrode composition, amount of dry mass, slurry solid content, comma gap, and calender roll gap, are directly utilised in the equations for the calculation. Also, certain assumptions are made to simplify the calculations. Based on these assumptions, a set of simplified mathematical equations that use these parameters is employed to derive the final output properties, which help streamline the calculation process. However, these parameters affect the cell energy density in ways other than how they are used in the cell energy density calculation, but they are too complex to represent their effects mechanistically. For example, mass loading is directly proportional to the comma gap. However, if the slurry's dynamic yield stress is exceeded during roll coating, variations in mass loading can occur due to the slurry dripping back into the roll . Therefore, all the chosen parameter values, including those not used for calculating cell energy density, are addressed by defining their minimum and maximum values (thresholds). These thresholds are set such that a reasonably processible product is achieved at every step of the manufacturing process. If the values the user selects do not fall within these thresholds of the different parameters, then feedback about that choice is provided to the user when the user tests the cell. These equations and assumptions are carefully selected to provide a general trend of the effects of various parameters considered. Their derivation is explained in the following sections.
