Cambridge, UK – Superdielectrics, a Cambridge-based energy storage technology firm, has officially launched its next-generation aqueous polymer battery, the Faraday 2. This unveiling marks a pivotal step towards delivering a compact, fridge-sized residential energy storage unit designed to significantly reduce household electricity expenditures, potentially by 85% or more. The Faraday 2 builds upon the foundational success of its predecessor, the Faraday 1 prototype, positioning the company at the forefront of scalable and sustainable energy solutions.

The proprietary technology, internationally patented by Superdielectrics, leverages advancements in contact lens polymers. Crucially, the Faraday 2 is constructed from abundant, non-toxic materials, entirely eschewing critical or rare earth metals, which are often associated with supply chain vulnerabilities and environmental concerns in conventional battery manufacturing. A notable operational feature is its rapid 30-minute full charge time, substantially faster than typical lithium-ion batteries. This efficiency is engineered to optimize the storage of surplus renewable energy, facilitating greater energy independence for homeowners and enabling participation in flexible tariff schemes. The innovation directly addresses the escalating demand for robust energy storage infrastructure within Europe's burgeoning renewable energy landscape, simultaneously offering a transformative pathway to lower consumer electricity costs and bolster energy security.

The Faraday 2 presents several compelling advantages over existing battery technologies. Safety is paramount, with approximately 50% of the technology being water-based, effectively eliminating the risk of thermal runaway, a significant fire hazard associated with lithium-ion counterparts. From a cost perspective, the reliance on readily available materials, rather than critical metals, translates to lower manufacturing expenses and more secure supply chains. Furthermore, the battery boasts enhanced sustainability due to its easily recyclable components and offers the potential for a longer operational lifecycle than current market offerings. While presently outperforming lead-acid batteries in energy density, ongoing research and development efforts are strategically aimed at surpassing the energy storage capacity of currently available lithium-ion solutions.

Jim Heathcote, CEO of Superdielectrics, emphasized the broader impact of the launch, stating, “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.” This sentiment was echoed by Julian Lennertz, Chief Commercial Officer at E.ON Next, a key partner. Earlier this year, Superdielectrics formalized a comprehensive collaboration agreement with E.ON, focusing on expediting the development and deployment of this battery solution. The immediate next phase involves the creation of larger prototypes for in-home customer trials, a strategic move aimed at extending access to safer, cleaner, and more affordable energy to millions of households.

The introduction of the Faraday 2 underscores Superdielectrics' strategic positioning within the global energy transition. As the imperative for efficient and sustainable energy storage intensifies, this aqueous polymer technology offers a compelling alternative to conventional battery chemistries, promising enhanced safety, reduced environmental footprint, and significant economic benefits for consumers. Its successful commercialization could reshape the residential energy storage market, providing a critical enabler for widespread renewable energy adoption and grid stability.
