摘要： Making a carbon aerogel involves 3-D printing an ink to make a printed part, removing the solvent from the printed part, and carbonizing the printed part (with the solvent removed) to make the aerogel. The ink is based on a solution of a resorcinol-formaldehyde resin (RF resin), water, and an organic thickener. Advantageously, the RF resin contains an acid catalyst, which tends to produce carbon aerogels with higher surface areas upon activation than those produced from methods involving an ink composition containing a base catalyzed resin.

摘要： Energized composites include vertically aligned graphene on carbon fibers (VGCF). The VGCF enhances surface area available for charge storage, acts as templates for depositing other charge storing materials and provides stability for a minimum of 100,000 discharge cycles. The final storage device is in the order of high strength carbon fiber matrix with active material, glass fiber separator with polymer electrolyte and another carbon fiber matrix with active material. To achieve higher voltage or current, devices can be connected in series or parallel, respectively. The whole structure is made into a structural component by infusing epoxy resin. An alternating pattern of energy storage devices allows for the epoxy resin to seep through the whole structure and strongly bind them to make a monolith multifunctional composite. The high strength energized composites can power any electrical devices including electric vehicles, portable electronics, and space vehicles without any tradeoff between energy and structural integrity.

摘要： Disclosed is a method for producing phthalocyanine-graphene hybrid materials which are covalently bonded by one step and one-pot electrochemical method. The method allows production in one step and does not require a purification procedure. The method includes the process steps of preparing an electrolyte solution having a phthalocyanine compound desired to be obtained simultaneously on a surface of the graphite working electrode, immersing the graphite working electrode into the electrolyte solution, performing a positive potential scanning on the graphite working electrode, converting the graphite working electrode into graphene oxide, converting the graphene oxide into the graphene, bonding the phthalocyanine compound to the graphene covalently in a potential working range scanned simultaneously and enhancing the bonding during the ongoing cycles, obtaining the covalently bonded phthalocyanine-graphene hybrid material obtained based on the applied potential range on the electrode surface, or depositing in solution in powder form.

摘要： Embodiments of the presently disclosed technology provide a synergistic combination of a conjugated open-shell donor-acceptor polymer with a carbon-based compound (e.g., reduced graphene oxide) to produce a composite electrode material which demonstrates state-of-the-art capacitance and potential window, with excellent kinetics and cycle life. The conjugated open-shell donor-acceptor polymer may comprise a plurality of alternating electron-rich monomers (i.e., donors) and electron-deficient monomers (i.e., acceptors) bonded together via a conjugated backbone. The conjugated backbone may comprise a connection of n-orbitals of the plurality of monomers in alternating single and double bonds that facilitates unpaired electron delocalization—thereby stabilizing charge for the polymer. The carbon-based compound of the composite electrode material may provide porous, conductive scaffolds for the composite electrode material, resulting in electrodes scalable to microns-thick films with fast kinetics.

摘要： Methods are disclosed for manufacturing an electrode for use in a device such as a secondary battery. Electrodes may include a first layer having first active particles adhered together by a binder, a second layer having second active particles adhered together by a binder, and an interphase layer interposed between the first and second layers. In some examples, the interphase layer may include an interpenetration of the first and second particles, such that substantially discrete fingers of the first layer interlock with substantially discrete fingers of the second layer.

摘要： An ultracapacitor that is capable of exhibiting good properties even after being subjected to high temperatures, such as experienced during solder reflow, is provided. The ultracapacitor contains a housing having sidewalls that extend in a direction generally perpendicular to a base. An interior cavity is defined between an inner surface of the base and the sidewalls within which an electrode assembly can be positioned. To attach the electrode assembly, first and second conductive members are disposed on the inner surface of the base. The electrode assembly likewise contains first and second leads that extend outwardly therefrom and are electrically connected to the first and second conductive members, respectively. The first and second conductive members are, in turn, electrically connected to first and second external terminations, respectively, which are provided on an outer surface of the base.
