To satisfy the ever-increasing electrical needs of our technology-oriented society and faced with a lack of universal storage solution, any safe, clean and reliable way to store electricity could find a practical application from terawatts to microwatts production. All-organic batteries have great potential for a new generation of greener energy storage solutions. In particular, anionic rocking-chair batteries are attractive targets, since they can be completely metal-free. While such a configuration is not possible with most inorganic materials, organic compounds are ideal candidates. In this joint proposal, we will develop all-organic anionic rocking-chair batteries using organic small molecules as electrode materials and assess their electrochemical performance and power delivery capability. Novel negative and positive p-type organic electrode materials will be developed and (electrochemically) characterized by the group of Birgit Esser (University of Freiburg, Germany). Suitable electrolytes will be identified and the electrochemical performance of the novel electrode materials evaluated in half cells. The group of Philippe Poizot (IMN, France) will investigate electrochemical and aging mechanisms of the resulting electrodes using advanced spectroscopic tools. Using the best electrode materials, they will design and build thick electrodes and all-organic cells and evaluate their electrochemical performance and power delivery capability.
