Publication number: 20090130564Abstract: The present invention is a low-cost method for fabricating electrodes for batteries, electric double-layer capacitors (EDLC or supercapacitors) and hybrid electrical energy storage devices. for which by low contact resistance between the metal current collector and carbon-containing electrode enhances performance. The electrodes comprise at least two layers. The first layer is a highly conductive carbon material, such as graphite, fused into the metal current collector. The second layer is a polarizing carbon-containing electrode typically comprising a nanoporous carbon powder pressed or rolled with a binder, or a composite that includes active materials (for example oxides, sulfides), binder and conductive additives such as carbon, black.

Publication number: 20090117289Abstract: The present invention is a method and apparatus for applying coatings in a rarefied gaseous medium. A cold cathode electron gun is used to generate an electron beam, which is directed to a crucible containing initial solid materials in a vacuum chamber, thus generating an initial solid material vapor. Nitrogen reaction gas is bled into the vacuum chamber, and ionization of the nitrogen gas in high frequency discharge. Subsequent interaction of initial material vapor with nitrogen ions and atoms results in generation of solid product heating of the substrate. Condensation of the vapor on the surface of substrate generates a thin film of solid electrode or electrolyte. The resulting rate of deposition of thin film of vitreous solid electrolyte and LiPon solid electrolyte is substantially higher than can be achieved with a magnetron sputtering process.Type: ApplicationFiled: October 9, 2008Publication date: May 7, 2009Applicant: Enerize CorporationInventors: Elena M.

Publication number: 20090000656Abstract: The present invention involves the use of specially formulated polymers into which anti-static and conducting metal additives have been incorporated to create a flexible, optically transparent cover for mechanical protection of the incident light-facing surface of the photovoltaic cells. The polymer coating imparts higher conversion efficiencies to photovoltaic cells and modules and is resistant to the destructive effects of UV. In the preferred embodiment, the surface comprising a flexible optically transparent polymer cover has a relief or “crinkle coat” structure morphology comprising a random set of rounded ridge and valley features that impart higher conversion efficiencies to photovoltaic cells and modules due to a concentration affect. Application of the present invention yields mono-crystalline photovoltaic modules that have conversion efficiencies as high as 20%, or more, as compared to 13-14% for presently available commercial module designs.Type: ApplicationFiled: April 15, 2008Publication date: January 1, 2009Applicant: Enerize CorporationInventors: Elena M.

Publication number: 20080133156Abstract: The present invention is an integrated method and apparatus for determining the quality of electrochemical energy storage devices, especially batteries. The invention is based on an integrated usage of electromagnetic and ultrasonic energy to probe of the interior volume of the battery. The first probe is carried out when the battery is at an initial charged state. After the first probe stage, a discharge of the battery being diagnosed is carried out until the test battery is at a small fixed test charge value. Signals from the eddy current probes allow determination of the continuity of the discharge current during the discharge process. After the discharge of the battery, the above described test sequence is repeated. The resultant eddy current signal generated at the initial state of the battery and the gradients of the eddy current signal and of the ultrasonic signal versus the battery capacity is determined.Type: ApplicationFiled: October 30, 2007Publication date: June 5, 2008Applicant: Enerize CorporationInventors: Volodymyr Redko, Volodymyr Khandetskyy, Elena Shembel
