Patent number: 8472163Abstract: A current collector for use in an electric double layer electrochemical capacitor having a sulfuric acid electrolyte. The current collector uses a conducting carbon (e.g., graphite foil) basis with p-type conductivity. A protective film covers at least a portion of the graphite foil basis. The protective film is comprised of a conducting composite material made with a conducting carbon and a conducting organic polymer with p-type conductivity. The protective film is grown on the current collector basis such that it preferably fills the pores of the current collector basis. A lug portion of the current collector basis may be protected with an insulating polymer material.Type: GrantFiled: February 19, 2008Date of Patent: June 25, 2013Assignee: Universal Supercapacitors LLCInventors: Samvel Avakovich Kazaryan, Gamir Galievich Kharisov, Vladimir Alexandrovich Kazarov, Sergey Nikolaevich Razumov, Sergey Vitalievich Litvinenko

Patent number: 8120333Abstract: The present invention is directed to methods for the automatic charging of an electrochemical electrical energy storage device. Charging may be performed until a pre-assigned voltage increment value measured across the terminals of the storage device is reached. Recurrent periods of charging and rest may be employed, with measurements of voltage taken and voltage increment determined after the passage of an assigned quantity of electrical energy. Automatic completion of the charging process is provided for, irrespective of the design features and number of energy storage devices (e.g., capacitors) in a module, the initial state of charge and/or temperature of the storage device, or the value and/or time instability of the charging current.Type: GrantFiled: November 27, 2007Date of Patent: February 21, 2012Assignee: Universal Supercapacitors LLCInventors: Nikolai Fedorovich Starodubtsev, Vladislav Alekseevich Karpov, Viktor Alexandrovich Dronov, Samvel Avakovich Kazaryan, Vladimir I.

Patent number: 7919014Abstract: The present invention relates to the production of electrochemical capacitors with a DEL. The proposed electrodes with DEL are based on non-metal conducting materials, including porous carbon materials, and are capable of providing for high specific energy, capacity and power parameters of electrochemical capacitors. P-type conductivity and high concentration of holes in electrode materials may be provided by thermal, ionic or electrochemical doping by acceptor impurities; irradiating by high-energy fast particles or quantums; or chemical, electrochemical and/or thermal treatment. The present invention allows for an increase in specific energy, capacity and power parameters, as well as a reduction in the cost of various electrochemical capacitors with DEL. The proposed electrodes with DEL can be used as positive and/or negative electrodes of symmetric and asymmetric electrochemical capacitors with aqueous and non-aqueous electrolytes.Type: GrantFiled: November 27, 2007Date of Patent: April 5, 2011Assignee: Universal Supercapacitors LLCInventors: Samvel Avakovich Kazaryan, Gamir Galievich Kharisov, Sergey Nikolaevich Razumov, Sergey Vitalievich Litvinenko, Vyacheslav I.

Patent number: 7799099Abstract: A method of manufacturing a current collector for use in a capacitor (e.g., a DEL capacitor) having an aqueous or non-aqueous electrolyte, such as an aqueous sulfuric acid electrolyte. The conductive basis of the current collector is preferably, but not necessarily, comprised of lead or a lead alloy. The portion of the conductive basis that will be in contact with the electrolyte is provided with a protective layer that is created by deposition of one or more layers of one or more protective coating materials thereto. Each protective coating material is comprised of at least a conductive carbon powder and a polymer binder that is resistant to the electrolyte. Preferably, but not essentially, the protective coating material(s) are applied to the conductive basis in the form of a paste, which is subsequently subjected to a solvent evaporation step and a thermal treatment step.Type: GrantFiled: October 27, 2008Date of Patent: September 21, 2010Assignee: Universal Supercapacitors LLCInventors: Samvel Avakovich Kazaryan, Valery Pavlovich Nedoshivin, Vladimir Alexandrovich Kazarov, Gamir Galievich Kharisov, Sergey Vitalievich Litvinenko, Sergey Nikolaevich Razumov

Publication number: 20090040689Abstract: An electrode and a DEL capacitor formed therewith. The electrode will typically be a polarizable electrode, and may be formed of an activated carbon material having a substantially zero ash percentage and a low percentage of transition metals. In constructing a DEL capacitor employing such an electrode, a non-polarizable electrode formed from a lead dioxide/lead sulfate compound is preferably also used. The DEL capacitor may utilize an acid-based electrolyte, such as an aqueous sulfuric acid electrolyte. Consequently, the present invention also includes a current collector that preferably comprises a base material formed from a lead or a lead compound and a protective coating material that is resistant to an acid-based electrolyte. Preferably, the protective coating material is formed from a polymer base and a conductive dope that may thereafter be applied to the current collector base material by a variety of methods.Type: ApplicationFiled: October 28, 2008Publication date: February 12, 2009Applicant: Universal Supercapacitors LLCInventors: Valery Pavlovich Nedoshivin, Alexey Borisovich Stepanov, Sergey Vladimirovich Tarasov, Igor Nikolaevich Varakin, Sergey Nikolaevich Razumov

Patent number: 7446998Abstract: A current collector for use in a capacitor having an aqueous or non-aqueous electrolyte, such as an aqueous sulfuric acid electrolyte. The conductive basis of the current collector may be manufactured from a number of conductive metals but, preferably, is comprised of lead or a lead alloy. The portion of the conductive basis that will be in contact with the electrolyte is provided with a protective layer that is created by deposition of one or more layers of one or more protective coating materials thereto. Each protective coating material is comprised of at least a conductive carbon powder and a polymer binder that is resistant to the electrolyte. Preferably, but not essentially, the protective coating material(s) are applied to the conductive basis in the form of a paste, which is subsequently subjected to a solvent evaporation step and a thermal treatment step. The resulting protective layer is also substantially devoid of pores through which the electrolyte can permeate.Type: GrantFiled: February 22, 2006Date of Patent: November 4, 2008Assignee: Universal Supercapacitors LLCInventors: Samvel Avakovich Kazaryan, Valery Pavlovich Nedoshivin, Vladimir Alexandrovich Kazarov, Gamir Galievich Kharisov, Sergey Vitalievich Litvinenko, Sergey Nikolaevich Razumov
