On the use of LiCoO2 nanoparticles as storage material for redox flow battery
Abstract
Redoxflow storage technologies soared over the past decades, but still remains limited by the solubility of redox species. A promising alternative could be the semi-solid redox flow batteries (SSRFB) that recently came out and which consists in using insertion material particles in suspension as storage vector [1]. Such a SSRFB leads theoretically to both higher efficiency and capacity, along with reduced species crossover. Nonetheless, it carries at least two challenges: studying the electrochemical behavior of dispersed nanoparticles and solving ion conductive membrane issues usually used for such systems.
