E.ON, Superdielectrics develop polymer-based battery tech for residential storage applications

Energy supplier E.ON and energy storage technology firm Superdielectrics have joined forces to promote and develop a new battery technology for stationary storage applications.

The new BESS technology takes a unique approach by using a polymer-based technology, with the main component being a membrane similar to contact lens materials. According to the two companies, these polymer batteries are both more affordable and more environmentally friendly than their lithium-ion erparts.

Superdielectrics unveiled their Faraday I polymer-based battery last year, and now E.ON will  work together with the company to upgrade, develop and promote the technology. The technology is aimed at giving customers more control of their home energy use, and Superdielectrics estimates that its technology could save consumers up to 85% on their domestic energy bills. E.ON will be using its data on the energy needs and usage of its millions of customers, including a number of EV owners, to help Superdielectrics fine-tune its technology for home use.

According to Superdielectrics, the battery can be fully charged in as little as half an hour, compared to multiple hours for other battery types, does not rely on rare earth metals to build, is made from readily available non-flammable materials that are easily recyclable, and has a comparable lifespan to existing battery technology.

Superdielectrics has stated that it is currently working on major upgrades to the technology in an effort to move towards commercial development, and has said that it intends to make an important announcement about the development of its technology later this year.

Jim Heathcote, chief utive of Superdielectrics said that the support and insight of “globally respected energy group” E.ON will enable the firm to bring the technology into production far sooner. He added: “We believe that our technology has the potential to revolutionise power generation and consumption and deliver enormous environmental and cost benefits to millions of people.”

Julian Lennertz, chief commercial officer at E.ON Next, agreed and added: “Superdielectrics’ technology could be a vital part of creating a cleaner, lower-cost energy future for everyone.”
