摘要:
An energy storage device comprising: two electrodes; and an electrolyte, wherein each of said two electrodes comprises an interpenetrating network of an electrically conducting polymer and an ionically conducting polymer, and wherein in said interpenetrating network each of said electrically conducting polymer and said ionically conducting polymer forms a continuous phase, and said two electrodes are each in the form of a freestanding film.
摘要:
Flexible and stretchable supercapacitors are made using carbon nanostructures produced by providing a first composite structure which includes a temporary substrate and an array of carbon nanotubes arranged in a stack on a surface of the temporary substrate such that the stack of carbon nanotubes is oriented generally perpendicular to the surface of the temporary substrate, which may include silicon dioxide. The stack of carbon nanotubes is transferred from the temporary substrate to another substrate, which includes a curable polymer, thereby forming another composite structure comprising the stack of carbon nanotubes and the cured polymer. (FIG. 1 (c)).
摘要:
A process for producing a supercapacitor electrode, comprising (a) subjecting multiple particles of MCMBs to a chemical activation with an activating agent selected from an acid, a base, or a salt at a temperature from 100°C to 1,200°C for a period of 0.5 to 24 hours sufficient to produce multiple porous particles each of a monolithic 3D graphene structure comprising multiple pores and a continuous 3D network of graphene pore walls comprising continuous or naturally interconnected graphene ligaments of 1-20 graphene planes of carbon atoms; (b) producing a suspension containing these multiple porous particles, an optional conductive additive, and an optional resin binder in a liquid medium; and (c) depositing the suspension onto at least a primary surface of a current collector to form a wet layer and removing liquid medium from the wet layer to form the supercapacitor electrode.
