This study investigates the enhancement of supercapacitor energy density by exploring role carbon aerogel (CA) electrode pore size and aqueous electrolyte compositions employing a combination experimental techniques molecular dynamics simulations. Supercapacitors, known for their rapid charge–discharge cycles longer lifespans, face challenge lower compared to lithium-ion batteries. To address this, recent state-of-the-art advancements have focused on optimizing architecture, such as hierarchical porous structures, fine-tuning maximize ion-transport efficiency capacitance. Our research integrates these modern strategies leveraging high-fidelity 3D modeling pores at different quench rates guide synthesis CA electrodes with precise distributions. We assessed performance optimized in systems using cutting-edge electrolytes, including 3 M KOH 1 Na2SO4, both recognized current high ionic conductivity compatibility materials. Notably, KOH-based system demonstrated superior specific capacitance, attributed increased surface area enhanced ion accessibility K+ OH– ions within structure. The capacitance values measured experimentally A/g (119 F/g) showed strong correlation simulation predictions (128 F/g), underscoring accuracy predictive power computational design.
