HIGH-ENERGY-DENSITY, NONAQUEOUS, REDOX FLOW BATTERIES HAVING IODINE-BASED SPECIES

摘要

Nonaqueous redox flow batteries (RFBs) can utilize a metal and a cation of the metal (Mn+) as an active redox couple for a first electrode and electrolyte, respectively, in a first half-cell. The RFBs can also utilize a second electrolyte having l-based species. The l-based species can be selected from the group consisting of h anions, I2, anions of lx (x > 3), or combinations thereof. Two different ones of the l-based species compose a second redox active couple in the second half cell.
