Sustainable All-Organic Redox-Flow Batteries for Stationary Application based on Aqueous Electrolytes

Call Reference: 
LC-NMBP-26-2018
Short description of project idea : 
The goal of the projects is to develop an all-organic redox flow battery based on aqueous electrolytes with reduced costs per kWh and cycle and high safety for storage of sustainable energy. Redox-flow batteries are till now one of the most promising storage technologies for renewable energies due their unique feature of an independent scalability of power and capacity as well as their long lifetime, fast response and capability of storing electric energy for several hours. However, the breakthrough of the state-of-the art Vanadium-RFB is hampered by relatively high costs in combination with low energy densities. Additionally, the price of vanadium is strongly dependent on the high-performance steel production. To circumvent these issues metal-free active materials based on organic compounds should be investigated. However, in order to reach the goal of the cost reduction the whole system (active materials, membranes, stack design, battery management system) has to be optimized.

Name of the organisation: 
Laboratory of Organic and Macromolecular Chemistry, Center for Energy and Environmental Chemistry Jena (CEEC Jena), Friedrich-Schiller-University Jena
Short description of organisation: 
The Center for Energy and Environmental Chemistry Jena (CEEC Jena) was founded in 2014. This center combines the research of the Friedrich Schiller University Jena and the Fraunhofer Institute for Ceramic Technologies and Systems Hermsdorf (IKTS) in the field of energy and envi-ronmental research. In total 18 groups investigate in this interfaculty institute new materials and technologies for energy storage. In this context, polymeric (“plastic”) materials offer great possibilities for the fabrication of energy storage devices – from the small scale (e.g., printable batteries) up to the large scale (e.g., polymer-redox flow batteries – pRFBs and organic redox flow batteries - oRFB). The utilization of the organic material circumvents the usage of toxic/harmful and often critical raw materials (e.g., cobalt, vanadium, lead).
