More safety for cell phone batteries

Fraunhofer researchers will be presenting a novel lithium-ion battery at Hannover Messe on April 21 - 25. It is based on a polymer electrolyte, which is – unlike the liquid electrolyte in conventional lithium-ion batteries – not inflammable. A test set-up for redox flow batteries will also be on display at the show. This makes it possible to compare different redox systems in a single test set-up.
