Quick charging super-capacitor technology revealed for clean energy storage

Professionals from the University of Surrey affirm that they are a step closer to fulfill their vision of clean energy storage post revealing their innovative super-capacitor technology that is capable to store and provide electricity at high power prices, specifically for mobile applications. 

In a newspaper published by the journal Energy and Environmental Materials, experts from Surrey’s Advanced Technology Institute (ATI) disclosed how their latest technology which has the ability to revolutionize energy consumption in electric vehicles and lower renewable-based energy loss in the national network. The experts also believe their technology can help thrust ahead of the progress of wave, solar, and wind energy by smoothing out the periodic nature of energy sources. 

ATI’s supercapacitor technology is built on a material which is known as Polyaniline (PANI), and this material  stores energy through a mechanism called as “pseudocapacitance.” This inexpensive polymer material can be utilized as an electrode in a super-capacitor device and is also conductive. This electrode stores change by seizing ions within itself by trading electrons with ion, which “dopes” the substance. 

In their paper, thee experts describe details of how they produced anew three-layer composite by using PANI, hydrothermal carbon, and carbon nanotubes that show the exceptional rate-capability at large entry densities, irrespective of the power use. 

Ash Stott, the head scientist on this project and a Ph.D. student from the University of Surrey, stated: “The future of global energy will depend on consumers and industry using and generating energy more efficiently and super-capacitors have already been proven to be one of the leading technologies for intermittent storage as well as high-power delivery. Our work has established a baseline for high energy devices that also operate at high power, effectively widening the range of potential applications.”

Professor Ravi Silva, Director of the ATI at the University of Surrey, mentioned: “This highly ambitious and impactful work has the potential to change the way we all live our lives — and it might be what is needed to make the change for an efficient and fast charging solution of harvested energy from the environment. We see this having an impact in all sorts of industries — from all wearable technology to mobile Internet of Things applications that will launch the 5G revolution. The potential for our super-capacitor is limitless.”
