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.

为了满足我们以技术为导向的社会不断增长的电力需求，并面临缺乏通用存储解决方案的问题，任何安全，清洁和可靠的电力存储方式都可以找到从太瓦到微瓦生产的实际应用。全有机电池在新一代绿色能源存储解决方案方面具有巨大潜力。特别是，阴离子摇椅电池是有吸引力的目标，因为它们可以完全不含金属。虽然这种配置对于大多数无机材料是不可能的，但有机化合物是理想的候选物。在这项联合提案中，我们将开发使用有机小分子作为电极材料的全有机阴离子摇椅电池，并评估其电化学性能和功率输送能力。Birgit Esser（弗赖堡大学，德国）小组将开发和（电化学）表征新型的负和正p型有机电极材料。将确定合适的电解质，并在半电池中评价新型电极材料的电化学性能。Philippe Poizot（IMN，法国）的团队将使用先进的光谱工具研究所得电极的电化学和老化机制。使用最好的电极材料，他们将设计和构建厚电极和全有机电池，并评估其电化学性能和功率输送能力。
