Cambridge, UK based Superdielectrics Group Plc has developed a breakthrough energy storage technology. The new technology stems from an ongoing collaboration with leading researchers at the University of Bristol who identified and validated the key mechanisms involved.
The Company’s vision is to create affordable, sustainable, energy systems. This could mean affordable grid independent energy anywhere in the world. Such systems require economically viable energy storage. The energy storage market is currently dominated by lithium-ion and lead-acid batteries. The Company’s patented new polymer-based energy storage technology solves the issue of dealing with rapidly fluctuating and intermittent renewable energy which makes it difficult to store solar and wind energy economically.
Superdielectrics’ energy storage technology combines electric fields (physics) and conventional chemical storage (chemistry) to create a new aqueous polymer-based energy storage technology. The Company is today formally launching the Faraday 1, its state-of-the-art hybrid energy storage technology. The technology behind the Faraday 1 has completed over 1 million hours of testing to create a system that already has the ability to significantly out perform lead-acid batteries and has the potential, with further development, to match or exceed existing Lithium-ion batteries.
The technology behind Faraday 1:
- Aqueous polymer-based technology that solves the issues of storing fluctuating and intermittent renewable energy.
- Highly efficient store of energy that charges over 10 times faster than lead-acid batteries with high cycle life.
- Safe store of energy – negligible fire risk.
- Low costs – uses readily available abundant raw materials.
- Recyclable.
- Huge scale of addressable opportunity with $50bn/year lead-acid battery market including electric scooter, forklift and off grid markets.
Jim Heathcote, CEO of Superdielectrics, commented:
“The team at Superdielectrics has worked incredibly hard to develop a ground-breaking technology that has the potential to revolutionise the energy storage market. Our breakthroughs deliver the potential, at last, to create the sustainable, global decentralised energy systems that the world desperately requires.
The properties that our technology possess enables it to compete with and exceed current solutions in the energy storage arena across a number of key metrics whilst leading the way in sustainability, recyclability and affordability.
This is a remarkable achievement by all concerned and we now look forward to commercialising our platform and products – we have seen global interest in our technology.”
Professor Marcus Newborough, Director of R&D of Superdielectrics, commented:
“The combination of the benefits of rapid charging and sustainability used for energy storage now make it possible to create worldwide affordable and clean energy systems.
In the future, the continuing development of our pure supercapacitor technology could surpass all existing battery technologies.”
Professor David Fermin, Head of the Bristol Electrochemistry and Solar Team and Net Zero Ambassador for the University of Bristol, added:
“It is a privilege to be part of the most exciting technology in the energy sector that I have seen involving our organisation. These state-of-the-art supercapacitors have the potential to become a game-changer in energy storage. Superdielectrics’ devices are not only highly competitive against mature technologies in terms of energy and power density, but they are also free of critical elements, using earth-abundant materials with a lower environmental impact than other energy storage technologies. I can see Superdielectrics developing into a major player in this global market, providing safe and affordable sustainable energy for everyone.”
Professor Phil Taylor, Pro Vice-Chancellor Research and Enterprise from the University of Bristol, said:
“Superdielectrics’ technology offers a new route to developing a clean energy system.”
