The 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.

With the demand for renewable energy surging, the Faraday 2 positions Superdielectrics at the forefront of the global energy transition.

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 per cent 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.

The 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.

Jim Heathcote, CEO of Superdielectrics, said: “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.”

Earlier this year, Superdielectrics announced a wide-ranging collaboration agreement with E.ON, one of the UK’s leading energy providers. The partnership is focused on accelerating the development and deployment of Superdielectrics’ battery solution, with the next step being the creation of larger prototypes that can be trialled in customers’ homes. This collaboration aims to give millions of homes access to safer, cleaner, and more affordable energy.

Julian Lennertz, Chief Commercial Officer at E.ON Next, said: “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.”
