Superdielectrics has launched its next generation aqueous polymer battery, marking a significant technological upgrade. Introducing the Faraday 2.
This launch marks a major milestone in the company’s mission to revolutionise energy storage with a safer, more sustainable, and cost-effective alternative to traditional lithium-ion batteries. The Faraday 2 builds on the success of the Faraday 1 prototype, being a major step towards the offering of a fridge-sized residential energy storage unit capable of reducing household electricity bills by 85% or more.
Developed from advances in contact lens polymers, Superdielectrics’ internationally patented technology uses abundant, non-toxic materials and contains no critical or rare earth metals. With a full charge time of just 30 minutes, significantly faster than a traditional battery, the Faraday 2 is designed to store surplus renewable energy efficiently, enabling flexible tariffs and greater energy independence for homes. This innovation addresses the growing need for scalable energy storage across Europe’s rapidly expanding renewable energy sector, and also offers a transformative solution to lower electricity costs, enhancing energy security.
Key advantages of the Faraday 2 include:
- Safe: Unlike lithium-ion batteries, approximately 50% of the technology is water-based, eliminating the risk of thermal runaway which is a fire-safety hazard.
- Low cost: The technology does not rely on critical metals making its materials cheaper than lithium-ion batteries with securer supply chains.
- Sustainability: Built with readily available, materials that are easily recyclable.
- Long lifecycle: Potential for even longer use than existing batteries.
- Energy density potential: Currently outperforming lead-acid batteries and with ongoing R&D efforts to surpass currently available lithium-ion energy storage capacity in the future.
Jim Heathcote, CEO of Superdielectrics, commented:
“The launch of Faraday 2 is a major step towards a low cost and clean energy future, as well as a key milestone for us as we work towards a commercial product. As the world shifts towards renewable energy, storage is the technological bottleneck. Our technology is low cost, safe and recyclable, helping the world in the global transition to sustainable energy.”
Julian Lennertz, Chief Commercial Officer at E.ON Next, commented:
“The transition to cleaner energy is about making that energy more affordable and sustainable, and our partnership with Superdielectrics is one of a huge number of ways we are working to help customers take control of their energy by making energy storage widely available. We are delighted to be a part of the Superdielectrics journey, sharing insight into how millions of customers use energy and what they need to benefit from a smarter energy system. The launch of Faraday 2 is an important milestone in the evolution of battery design using readily available materials – and is yet another world-leading innovation designed and developed in the UK.”
