Supercapacitors

The explosion of mobile electronic devices, electric vehicles, drones and other technologies have driven demand for new lightweight materials that can provide the power to operate them. Researchers have reported a structural supercapacitor electrode made from reduced graphene oxide and aramid nanofiber that is stronger and more versatile than conventional carbon-based electrodes.

Experts from the University of Surrey believe their dream of clean energy storage is a step closer after they unveiled their ground-breaking super-capacitor technology that is able to store and deliver electricity at high power rates, particularly for mobile applications.

A new supercapacitor based on manganese oxide could combine the storage capacity of batteries with the high power and fast charging of other supercapacitors, according to researchers.

As demands for lighter and smaller wearable devices and high functional IoT gadgets rise, there is a growing need for new technologies for power collection, storage, management.

A tiny microsupercapacitor that is as small as the width of a person's fingerprint and can be integrated directly with an electronic chip has been developed. This has attracted major attention as a novel technology to lead the era of Internet of Things since it can be driven independently when applied to individual electronic components.

Researchers demonstrate robust supercapacitors that still work when stretched to eight times their original size.

While at the proof-of-concept stage, it shows enormous potential as a portable power supply in several practical applications including electric vehicles, phones and wearable technology.

Vehicles for construction, agriculture and mining CAM have become one industry served by giants such as Caterpillar, CNH Industrial, John Deere and Komatsu but also small businesses making the new requirements such as drone systems and weeding and mine survey robots.

NAWA Racer is inspired by 1960s café racers but is powered by a world-first 'hybrid' battery system, which combines next-gen ultracapacitors with lithium-ion offering ten times more power and five times more energy than existing ultracapacitors.
