New battery tech hailed “game-changer” for energy storage

A cutting-edge energy storage technology claimed to have the potential to revolutionise the battery market has been launched by green energy company Superdielectrics Group Plc.

A cutting-edge energy storage technology claimed to have the potential to revolutionise the battery market has been launched by green energy company Superdielectrics Group Plc.

This new technology stems from an ongoing collaboration with researchers at the University of Bristol who identified and validated the key mechanisms involved.

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 says the technology behind its Faraday 1 has completed over one million hours of testing to create a system it says already has the ability to “significantly outperform” lead-acid batteries, and has the potential, with further development, to match or even better existing Lithium-ion batteries.

Jim Heathcote, chief executive of Superdielectrics, claims the technology 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,” he added. “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.”

The Faraday 1 consists of an aqueous polymer-based technology that is claimed to solve the issues of storing fluctuating and intermittent renewable energy. Furthermore, Superdielectrics says, it also offers:

  • Highly efficient store of energy that charges over 10 times faster than lead-acid batteries with high cycle life
  • Safe store of energy – and negligible fire risk
  • Low costs – it uses readily available, abundant raw materials
  • Recyclable
  • Huge scale of opportunity with $50bn/year lead-acid battery market including electric scooter, forklift and off grid markets

Professor David Fermin, head of the electrochemistry and solar team at Bristol University, and its net zero ambassador, worked with a team of Bristol engineers, examining the performance of prototype devices, and unravelling the mechanisms involved in the storage and release of energy.

He said: “These state-of-the-art supercapacitors have the potential of becoming a game changer in energy storage. Superdielectrics’ devices are not only highly competitive against matured technologies in terms energy and power density, but are also free of critical elements, using earth abundant materials with lower environmental impact than other energy storage technologies.”

Professor Phil Taylor, the university’s pro vice-chancellor research and enterprise, added: “Superdielectrics’ technology offers a new route to developing a clean energy system.”

According to Dr Alistair Hales from Bristol’s School of Electrical, Electronic & Mechanical Engineering, a key aspect of this new better technology is its ability to discharge “close to 100%” of the charge stored, compared to conventional battery systems; “even in very high power applications and without significant long-term degradation to the performance”.

Professor Marcus Newborough, director of R&D of Superdielectrics, added: “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.”
