Influence of structural modifications on the alkali ion storage properties of carbon black in hybrid ion capacitor negative electrodes
Structurally altered carbon blacks were investigated in hybrid ion capacitors. A diffusion limited storage in more graphitic structures is observed for Na. Li shows no diffusional hindrance and higher rate capability with graphite-like carbons.
