摘要： An ultracapacitor that comprises a first and second electrochemical cell that are connected in parallel is provided. The cells are define by a first electrode that contains a current collector having opposing sides coated with a carbonaceous material, a second electrode that contains a current collector having opposing sides coated with a carbonaceous material, and a separator positioned between the first electrode and the second electrode. The second cell is by the second electrode, a third electrode that contains a current collector having opposing sides coated with a carbonaceous material, and a separator positioned between the second electrode and the third electrode. The ultracapacitor also contains a nonaqueous electrolyte that is in ionic contact with the electrodes and contains a nonaqueous solvent and an ionic liquid. A package encloses the first cell, the second cell, and the nonaqueous electrolyte.

摘要： A supercapacitor module is provided. In some implementations, the supercapacitor module may include a first supercapacitor having a first parameter value for a capacitor parameter in a first test condition. The supercapacitor module may include a second supercapacitor having a second parameter value for the capacitor parameter in about the first test condition. A ratio of the second parameter value to the first parameter value may be from about 0.8 to about 1.2. The supercapacitor module may prevent overvoltages across the first and second supercapacitors, such that the supercapacitor module may satisfactorily operate without a balancing circuit.

摘要： Systems and methods of charging and discharging an ultracapacitor are disclosed. In one embodiment, a circuit for charging a capacitor can include a power source configured to provide a source voltage. The circuit can further include an ultracapacitor, a temperature sensing device, a power converter, and one or more control devices configured to receive signals indicative of a temperature from the temperature sensing device, and to control operation of the power converter based at least in part on the one or more signals indicative of the temperature.

摘要： A supercapacitor assembly is disclosed that includes a supercapacitor enclosed within a housing. The housing may have an outer surface and may be sealed at a seal location. A barrier layer may be formed on a portion of the outer surface that is adjacent at least one of the seal location or a surface to which the supercapacitor is mounted. The barrier layer may be a high performance polymer, such as a thermoplastic polymer or a thermoset polymer.

摘要： An ultracapacitor that contains at least one electrochemical cell is provided. The cell includes a first electrode that contains a first carbonaceous coating (e.g., activated carbon particles) electrically coupled to a first current collector, a second electrode that contains a second carbonaceous coating (e.g., activated carbon particles) electrically coupled to a second current collector, an aqueous electrolyte in ionic contact with the first electrode and the second electrode and that contains a polyprotic acid (e.g., sulfuric acid), and a separator that is positioned between the first and second electrodes. Through selective control over the particular nature of the materials used to form the ultracapacitor, as well as the manner in which they are formed, a variety of beneficial properties may be achieved.
