Abstract: 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 I-based species. The I-based species can be selected from the group consisting of I− anions, I2, anions of Ix (x≧3), or combinations thereof. Two different ones of the I-based species compose a second redox active couple in the second half cell.

Abstract: Modifications to the surface of an electrode and/or the surfaces of the electrode material can improve battery performance. For example, the modifications can improve the capacity, rate capability and long cycle stability of the electrode and/or may minimize undesirable catalytic effects. In one instance, metal-ion batteries can have an anode that is coated, at least in part, with a metal fluoride protection layer. The protection layer is preferably less than 100 nm in thickness. The anode material is fabricated according to methods that result in improved anode performance.

Abstract: Ionic conductive chromophores can be used as the positive electrolytes for high-energy density, nonaqueous redox flow battery (NRFB) systems. The nonaqueous nature of the NRFB systems allow for high operation voltage (compared to aqueous systems). Furthermore, the structure modifications to chromophores described herein improve the solubility of the resultant ionic conductive chromophores, thereby allowing them to be used in flow cell configurations.
