Polymers for energy storage

The research in this field is dedicated to

- Lithium ion batteries (cooperation with Daimler AG, Stuttgart)

- Redox batteries within the DFG SPP 2248 "Polymer-based Batteries" (cooperation mit Prof. U. S. Schubert, Dr. M. Hager, FSU Jena, und Dr. P. Uhlmann, IPF).

The projects aim at development of new polymer electrolyes for solid state batteries, the former for lithium ion batteries, and the latter for organic Redox solid state batteries. This project also includes the development of  triblock copolymers by a modular approach using anionic and controlled radical polymerization for application as "molecular battery".

- Self-supporting film of polymeric electrolyte -

- Ionic conductivity of polymeric electrolyte networks -
