Understanding the effects of processing on the performance of Li-ion batteries is essential to the development of optimal battery technology. In this work, the non-idealities of microstructural properties of porous battery electrodes, such as particle morphology and compaction are numerically simulated to predict the power and energy response of porous battery systems. Here, by extending the well-known dualfoil software, a physical framework has been created to account for the effects of microstructural non-idealities on relevant battery design parameters, such as reactive area density and through-thickness tortuosity. The effect of particle alignment (texture) and particle morphology on the specific power and energy density are quantified and rationalized. Optimal aspect ratios for improved battery performance are proposed and discussed.
