Despite extensive research over the past two decades, achieving simultaneous high energy and power density in supercapacitors (SCs) remains a challenge. The key lies in designing nanoporous networks that offer a very high surface area while also maximizing electrolyte-ion accessibility of the pores. However, experimentally measuring pore accessibility in supercapacitor electrodes is challenging. This study employs a Particle-In-Cell-based computational approach to simulate charge transport, gove
