FLOWING ELECTROLYTE BATTERY CELL STACK HAVING AN IMPROVED FLOW DISTRIBUTION ZONE

摘要

A flowing electrolyte battery cell stack (700) as provided enables improved distribution of electrolyte. The cell stack (700) includes a casing having a plurality of half cells (805) inside the casing defining a positive polarity end and a negative polarity end of the casing. Each half cell includes an electrode plate (705) and an adjacent separator plate (715). A flow distribution zone (830) is connected to an electrode cavity of the half cell (805) defined between the electrode plate (705) and the adjacent separator plate (715) for evenly distributing electrolyte through the half cell (805). The flow distribution zone (830) includes a first bifurcation (910). A trunk (905) of the first bifurcation (910) is connected to an end of a capillary tube (727), and a plurality of second bifurcations (925). A trunk (920) of each second bifurcation (925) is connected to a branch (915) of the first bifurcation (910).
