Abstract: All-vanadium sulfate redox flow battery systems have a catholyte and an anolyte comprising an aqueous supporting solution including chloride ions and phosphate ions. The aqueous supporting solution stabilizes and increases the solubility of vanadium species in the electrolyte, allowing an increased vanadium concentration over a desired operating temperature range. According to one example, the chloride ions are provided by MgCl2, and the phosphate ions are provided by (NH4)2HPO4.

Abstract: Disclosed are cathodes having electron-conductive high-surface-area materials, aqueous non-halide-containing electrolytes, secondary zinc-iodine energy storage devices using the same, and methods for assembling the same. The disclosed high-surface-area materials and the aqueous non-halide-containing electrolyte solutions can contribute together to the confinement of the active iodine species in the cathode and to the minimization of shuttle effects and self-discharging. The non-halide-containing electrolyte salts can facilitate preferential adsorption of the iodine species to the cathode material rather than dissolution in the aqueous electrolyte solution, thereby contributing to the confinement of the active iodine species.

Abstract: Composite separators having a porous structure and including acid-stable, hydrophilic, inorganic particles enmeshed in a substantially fully fluorinated polyolefin matrix can be utilized in a number of applications. The inorganic particles can provide hydrophilic characteristics. The pores of the separator result in good selectivity and electrical conductivity. The fluorinated polymeric backbone can result in high chemical stability. Accordingly, one application of the composite separators is in redox flow batteries as low cost membranes. In such applications, the composite separator can also enable additional property-enhancing features compared to ion-exchange membranes. For example, simple capacity control can be achieved through hydraulic pressure by balancing the volumes of electrolyte on each side of the separator. While a porous separator can also allow for volume and pressure regulation, in RFBs that utilize corrosive and/or oxidizing compounds, the composite separators described herein are preferable for their robustness in the presence of such compounds.
Abstract translation: 具有多孔结构并且包含在基本上完全氟化的聚烯烃基质中的酸稳定的，亲水的无机颗粒的复合隔膜可用于许多应用中。 无机颗粒可以提供亲水性。 分离器的孔导致良好的选择性和导电性。 氟化聚合物骨架可导致高的化学稳定性。 因此，复合隔板的一个应用是作为低成本膜的氧化还原液流电池。 在这种应用中，与离子交换膜相比，复合分离器还可以实现额外的性能增强特征。 例如，通过平衡分离器两侧的电解液的体积，可以通过液压来实现简单的容量控制。 虽然多孔分离器还可以允许体积和压力调节，但是在使用腐蚀性和/或氧化性化合物的RFB中，本文所述的复合隔膜在其存在下的稳健性是优选的。

Abstract: Improved metal-based redox flow batteries (RFBs) can utilize a metal and a divalent cation of the metal (M2+) as an active redox couple for a first electrode and electrolyte, respectively, in a first half-cell. For example, the metal can be Zn. The RFBs can also utilize a second electrolyte having I−, anions of Ix (for x≧3), or both in an aqueous solution, wherein the I− and the anions of Ix (for x≧3) compose an active redox couple in a second half-cell.
