Maxwell offers postage stamp size PC-10 super cap
Roughly the size of a postage stamp and able to efficiently store power and distribute it immediately, the PC-10 provides up to 10 years or more of reliable data protection for high-performance solid-state drives (SSD) and non-volatile memory modules in enterprise storage systems in the event of power disruptions while reducing the overall cost of ownership and environmental impacts of conventional battery solutions.
Panasonic Goldcaps provide backup and peak power solution
Electric Double Layer Capacitors provide Backup and Peak Power. Either as a battery replacement or in combination with a battery as battery backup, they use a physical mechanism that generates a double electric field which acts like a dielectric, hence the name Electric Double Layer Capacitors. The brand name for the Panasonic EDLC´s is “Goldcap” and indicates the leading position for the small sized EDLC´s.
Bringing Batteries and Capacitors Together - EEJournal
Batteries and capacitors have existed – and co-existed – for a long time. Your typical basic electronics course will probably teach them in different chapters or on different pages because they’re so different: batteries are used to power a circuit; capacitors handle all manner of jobs from establishing timing in RC circuits to helping figure out where the poles and zeros go in an analog circuit to stabilizing the power rail.
Researchers Use DVD Burner to Fabricate Microcapacitors
UCLA researchers have designed a new way to fabricate microcapacitors that could provide a more efficient and cost-effective way to provide energy sources for micro devices that charge 100 to 1,000 times faster than standard batteries.
Change of Global Market Value of Supercapacitors?
Energy Harvesting Journal- Maxwell Technologies, which has been the leader in supercapacitors worldwide, has been overstating its results by improperly recording certain sales through distributors. It has made the following statement, “Maxwell believes that the restatement of revenue related to these distributors will decrease previously reported revenues for fiscal year 2011 by approximately $6.5 million and decrease revenues in the first three quarters of 2012 by approximately $5.5 million in the aggregate”. Most of Maxwell’s overall revenue relates to supercapacitor sales, so how does this affect supercapacitor market forecasts? Leading analyst IDTechEx that has studied the supercapacitor/ultracapacitor market has been looking again at the figures and it concludes that Maxwell is not indicative of the overall industry.
Vent Assemblies For Electrochemical Double-layer Capacitors
Abstract: A container of an electrochemical double-layer capacitor includes a housing, a cap portion adapted to be coupled the housing, an orifice passing through one of the housing or the cap portion, and a vent assembly in fluid communication with the container and secured within the orifice. The housing and the cap portion define an interior envelope of the container, and at least a portion of the vent assembly is located inside the interior envelope of the container.
Method For Packaging And Connecting Ultracapacitors
Abstract: An ultracapacitor energy storage system and in particular a system for packaging and connecting ultracapacitors (15) for energy storage purposes is described which is applicable in automotive and stationary applications. The ultracapacitors (15) in the system can be in series or parallel or a Combination of both. A controller, relays, voltage monitoring and isolation fault detection are used to regulate the system. The mechanical construction of frame and different pluggable modules (2 and 7) lead to an easy in and de-installation of the different parts. The different constructions are designed with a safe handling by the operator in mind.
Hydrochloric Acid Washing For EDLC Conductive Ink
Abstract: Water-based conductive ink compositions may include acid-washed graphite particles, carbon black particles, at least one polymeric dispersant, at least one acrylic binder, at least one polyvinylpyrrolidone binder, at least one defoamer, and an aqueous carrier. At least 90 wt. % of the acid-washed graphite particles and the carbon black particles, based on the combined weight of the acid-washed graphite particles and the carbon black particles, may have particle sizes less than 10 μm.
