Superdielectrics, in collaboration with E.ON, is pioneering a next-generation polymer-based battery technology that merges the fast charging capabilities of supercapacitors with the energy retention of chemical batteries. This innovative approach utilizes a unique membrane material, inspired by contact lenses, to create a safer, cheaper, and more environmentally friendly alternative to traditional lithium-ion batteries. The core of their technology revolves around crosslinked hydrophilic polymers that form a robust three-dimensional matrix, permitting both electrochemical and electrostatic energy storage. Notably, the absence of lithium, cadmium, and cobalt in the composition contributes to the sustainability and recyclability of the battery system, which promises significant benefits in terms of affordability, safety, and minimal environmental impact.
Despite the promising claims, detailed technical specifications and performance metrics remain undisclosed. The company has, however, reported notable advancements, including a nine-fold increase in cell density over the past two years, and asserts that its battery can cycle in approximately 30 minutes with a lifecycle potentially surpassing that of existing batteries. Supported by E.ON’s extensive customer data, Superdielectrics aims to enhance home energy management, reduce electricity bills, and combat fuel poverty in the UK. With ongoing developments and anticipated announcements in late 2025, the firm is focused on refining its technology, striving to offer a competitive, sustainable, and efficient energy storage solution.
