Cost-effective, long-life redox flow batteries

An affordable way to store clean energy

Research News / 3.6.2019

Renewable energy sources can fluctuate in the amount of power they are able to provide – which is why batteries are used to temporarily store the energy. The problem with lithium ion batteries is their short service life, while redox flow batteries have, to date, been cost-prohibitive. Now, however, innovative new redox flow systems are available at the same price point as lithium ion batteries, and last twice as long. Volterion is a spin-off of the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT, and has succeeded in dramatically reducing the manufacturing costs involved.
