Supercapacitors

Research shows potential ways to manufacture graphene-based nano-inks for additive manufacturing of supercapacitors in the form of flexible and printable electronics.

Scientists have created a new generation of low-cost, high-energy supercapacitors to power electric vehicles. Researchers have produced a cheaper, more sustainable and energy-dense electrode material for supercapacitors which could pave the way for wider market penetration of this high-power, quick charging electric vehicle technology.

The prototype will feature a world-first in electric powertrains: a 'hybrid' battery which combines Nawa Technologies' own ultracapacitors, NAWACap, with conventional lithium-ion cells.

Exploration of extremely cold environments, from Earth's polar regions to the moon and Mars, requires technology that can rapidly store and deliver electricity at ultralow temperatures. NASA's Perseverance rover, for example, needs heaters to keep the rover's battery system from freezing in Martian temperatures averaging about -81 F (-62 C).

A sustainable, powerful micro-supercapacitor may be on the horizon. Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their electrodes — the connections responsible for managing the flow of electrons during charging and dispensing energy. Now, researchers have developed a better material to improve connectivity while maintaining recyclability and low cost.

In a step towards a new type of energy storage, researchers have developed a hybrid supercapacitor that offers the best of both worlds in energy storage.

A team working has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries.

Other than a spicy night snack, the crayfish has been endowed with greater significance. Research has made it possible to use crayfish shell as the biological template for high-performance supercapacitors.

An alternative to batteries, micro-supercapacitors are energy storage devices that can complement or replace lithium-ion batteries in wearable devices. Micro-supercapacitors have a small footprint, high power density, and the ability to charge and discharge quickly.
