Abstract
Provided is a supercapacitor electrode, comprising: (a) preparing a deformable mass of multiple flakes of exfoliated graphite worms or expanded graphite dispersed in or impregnated by a liquid or gel electrolyte; and (b) subjecting the deformable mass to a forced assembling and orientating procedure, forcing the deformable mass to form the electrode, wherein these fakes are spaced by thin electrolyte layers, having an electrolyte layer thickness from 0.4 nm to 10 nm, and the flakes are substantially aligned along a desired direction, and wherein the electrode has a physical density from 0.5 to 1.7 g/cmand a specific surface area from 50 to 3,300 m/g, when measured in a dried state of the flakes without the electrolyte. This supercapacitor has a large electrode thickness, high active mass loading, high tap density, and exceptional energy density.
