报告摘要:
Flow battery dueto its good safety, long life time, good scalability and flexibility, isbelieved as one promising system for large scale energy storage. Because thevolumetric electron transfer number of solid active materials is much higherthan that of soluble species in electrolytes, so the energy density is boostedmuch if solid active materials can be introduced in flow batteries. Redoxtargeting based Li-X flow batteriesutilize redox reactions to realize energy storage in solid materials. Two mainsystems are developed based on redox targeting reactions: redox flow Li-ionbattery and redox flow Li-O2 battery. In this talk, the workingprinciple, the advantages, and the challenges of redox targeting based Li-X flow batteries will be carefullyintroduced. Through electrochemical spectroscopy, operando characterizationtechniques, we developed one way to estimate the efficiency of redox targetingreactions between redox molecules and target active materials. Based on ourprevious studies, the future development of redox targeting based Li-X flow batteries will be discussed.
