Optimizing the volumetric energy density of carbon-based supercapacitors involves attaining a high working voltage window and capacitance while ensuring optimal rate performance. Ionic liquids high-density porous carbons become emerging electrolytes electrode materials due to their decomposition large ion-accessible surface area, respectively. However, understanding impact ion diffusion pathways in carbon on performance proves challenging diverse microstructures materials. This research presents customized spherical nanocarbon clusters functioning as material pouch-type ionic liquid supercapacitors, aiming enhance transport behavior within electrodes by modifying interlayer plane into intercluster pore pathways. The obtained morphologies, close arrangements, densities shorten pathway facilitate accessibility for better capability density. Using relative green approach, we employed non-volatile EMIMBF4 electrolyte combination carboxymethyl cellulose styrene-butadiene rubber aqueous binders electrodes. strategy resulted remarkable specific areal 0.091 F m−2, 53 cm−3 at 0.5 A g−1, impressive 22.73 Wh L−1 481.25 W 12.79 23020.85 L−1.
