Energy Storage

Grafoid Inc. to sign a two-year R&D agreement with the University of Waterloo to investigate and develop a graphene-based composite for electrochemical energy storage for the automotive and/or portable electronics sectors.

Cellergy super capacitors integrated with Sol Chip Energy Harvester showcase at Berlin Wireless Sensor Networks and Energy Harvesting Trade Show.

Taking a significant step toward improving the power delivery of systems ranging from urban electrical grids to regenerative braking in hybrid vehicles, researchers have synthesized a material that shows high capability for both the rapid storage and release of energy.

Maxwell Technologies, which has been the leader in supercapacitors worldwide, has been overstating its results by improperly recording certain sales through distributors.

Next week Energy Harvesting & Storage and WSN & RTLS Europe will open at the ICC Berlin, Germany on April 17-18 (www.IDTechEx.com/EH). The events are co-located with Printed Electronics Europe, Graphene LIVE! and Supercapacitors Europe - with over 1,400 people already pre-registered.

Scientists have now developed a nanomaterial which enables considerably more power to be stored in lithium ion batteries.

Expansion into state of the art power component manufacture, notably supercapacitors targeted for energy density greater than that of lead acid and NiCd batteries but with much longer life, greater reliability and much greater power density together with wider temperature range.

University of Manchester graphene researchers have been awarded a £3.5m funding boost that could bring desalination plants, safer food packaging and enhanced disease detection closer to reality.

Proteins on the surface of bacteria can produce an electric current by simply touching a mineral surface.

Experts in nuclear physics have helped develop research towards a 'nuclear battery', which could revolutionise the concept of portable power by packing in up to a million times more energy compared to a conventional battery.

Florida State University and Tallahassee-based General Capacitor LLC have signed an agreement for the development of a new supercapacitor technology destined to play a major role in the world's future energy usage and storage needs.

Supercapacitors replace lithium-ion batteries. Lithium-ion batteries replace nickel metal hydride and lead acid batteries. There are side stories of course. Some supercapacitors replace electrolytic capacitors and others create new applications. However, in this article, we concentrate on replacing lithium-ion batteries.

As we make the transition from fossil fuels to clean, renewable energy sources, one fact that becomes clear is that while fossil fuels provided both an energy source and a storage medium in one, in the new world of renewables, these two functions will have to be provided separately.

A stretchable lithium-ion battery -- a flexible device capable of powering their innovative stretchable electronics.

A new battery technology provides double the energy storage at lower cost than the batteries that are used in handheld electronics, electric vehicles, aerospace and defence.
