Abstract

A method of making a capacitor-assisted hybrid electrode for a lithium-ion electrochemical cell includes admixing a solvent, a cellulose-based dispersant, and a plurality of capacitive particles comprising carbon to form a dispersion. The cellulose-based dispersant forms hydrogen bonds with one or more carbonyl-groups on the capacitive particles comprising carbon. The dispersion is combined with an electroactive material, an electrically conductive material, and a binder to form a slurry. The slurry is applied to a current collector and solidified to form the capacitor-assisted hybrid electrode having a composite hybrid active layer on the current collector. Capacitor-assisted hybrid electrodes formed from such methods are also provided.
