Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm-2, without short circuit or voltage instability.Redox flow batteries that incorporate solid energy-storing materials are attractive for high-capacity grid-scale energy storage due to their high theoretical energy densities. However, their practical implementation is held back by low rate capability. Now, a group of researchers led by Albuquerque-based Sandia National Laboratories have ...Den vollständigen Artikel lesen ...
