Energy Storage

A groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors.

While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors.

The chemistry in Ambri's technology is different from any other currently used in batteries.

Cellergy is a developer of small supercapacitors for electronic applications. The company is currently under change of management given bad financial situation.

Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance.

The EnerSys and Ioxus' cooperation will focus on creating products to address regenerative braking and energy recovery in the material handling markets, and other major markets, including the UPS bridge to generator markets, the automotive and heavy truck critical and cold start markets, and the energy storage/power conditioning markets.

The ink is still drying on an agreement between Florida State University and Tallahassee-based General Capacitor LLC 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 (ultracapacitors) are now center stage for designers of electronics and particularly power circuits. This is because they are improving faster than the batteries and electrolytic capacitors they increasingly replace. More subtly, they reduce the need for and danger from lithium-ion batteries. For example, when placed across a rechargeable battery, they protect it from fast charging and discharging and allow more of the energy in the battery to be utilised. Learn more ...

Energy harvesting - harvesting abundant energy from the environment to power small devices or assist larger devices - has secured a sure foot-hold in building and industrial markets, powering wireless sensors to improve efficiency, reduce costs and increase automation.

The new chemistry promises to significantly boost energy density and meet the rigorous cycle life and reduced swelling battery requirements for thin mobile consumer electronics.
