Abstract
A redox flow battery includes a cathode, an anode, a charge-carrying electrolyte, and an (a) oxidized and a (b) reduced form of an active material. The active material has the following formula: (D)-(L)-(A)-[(L)-(A)]V-DZ(F1) or (D)-(L)-(A)-(L-D)X (F2). In these formulae, each D is covalently bonded to an L, each L is covalently bonded to an A, x is a number from 0 to 5, v is a number from 0 to 5 and z is 0 or 1. D is an electron donor compound, L is a linker, and A is an electron acceptor compound. Each of D, L, and A has a particular structure.
