High-energy density flow battery system with a smi-solid fluid containing chalcogens or metal chalgogenides

Abstract

This invention provides semi-solid electrolytes for use in redox flow batteries that have improved energy density and flow fluid properties. The battery systems of this invention contain an ionically conductive fluid, with electrode active particles suspended in the fluid that contain one or more elemental chalcogens, one or more metal chalcogenides, or a combination thereof. The fluid is substantially free of electronically conductive particles other than the chalcogens and chalcogenides. The battery system can be built with a flowable system for one or both electrodes. Prototypes of this invention have over twenty times more energy production per mass compared with previous battery technology, and can be recharged in a matter of minutes.
