Abstract: Processes for limiting circulation of precipitates in a redox flow battery system are described. The processes include filtering the negative electrolyte, or the positive electrolyte, or both in one or more filters. The filter(s) can be located in the negative electrolyte loop, the positive electrolyte loop, or in both loops. Filtering can take place in normal operation; it can also take place during refresh cycles.

Abstract: Various current collectors for redox flow batteries are described. The current collectors include at least one metal plate encapsulated in a conductive polymer end plate, the metal plate to the back of a stack end plate with a conductive adhesive, and a flat metal plate having deformable tabs. Battery flow systems incorporating the current collectors are also described. Battery flow systems with easily replaceable current collectors are also described.
