    摘要： A method of in-situ electrolyte preparation in a flow battery includes providing a vanadium-based electrolyte solution having vanadium ions of predominantly vanadium V4+ to a first electrode and a second electrode of at least one cell of a flow battery. The vanadium V4+ at the first electrode is converted to vanadium V3+ and the vanadium V4+ at the second electrode is converted to vanadium V5+ by providing electrical energy to the electrodes. A reducing agent is then provided to the vanadium V5+ at the second electrode to reduce the V5+ to vanadium the V4+. The vanadium V3+ at the first electrode is then converted to vanadium V2+ and the vanadium V4+ at the second electrode is then converted to vanadium V5+ by providing electrical energy to the electrodes. A simple method to produce predominantly vanadium V4+ electrolyte from a V5+ source, such as V2O5, is also taught.

    摘要： A method of sealing a multi-component bipolar plate is disclosed. The method may include inserting a first seal between a first component and a second component, wherein the first seal is aligned with a first plurality of protrusions formed on a surface of at least one of the first component and the second component. The method may also include compressing the first component and the second component to cause the penetration of the first plurality of protrusions into the first seal. The method may further include plastically deforming the first seal in order to create a first sealing surface between the first component and the second component.

    摘要： 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.

    摘要翻译： 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。
