Abstract: An electrode plate, method for manufacturing an electrode plate, and method of testing an electrode plate enable efficient production of robust flowing electrolyte batteries. The method of testing an electrode plate includes forming a frangible portion in the electrode plate; providing a seal around a periphery of the electrode plate, wherein the periphery extends across the frangible portion; applying a gas adjacent a surface on a first side of the electrode plate; and detecting whether there is a presence of the gas adjacent a surface on a second side of the electrode plate, if the electrode plate passes testing, the frangible portion is removed from the electrode plate to define a cut-away region. The electrode plate is then positioned in a battery cell stack including a plurality of other electrode plates. A manifold is then attached to the cell stack adjacent the cut-away region of the electrode plate.

Abstract: A flowing electrolyte battery can be quickly and safely electrically stripped using electrolyte. The battery includes: a stack comprising a plurality of electrodes; a negative electrolyte circuit coupled to the stack, for circulating negative electrolyte through the stack; a positive electrolyte circuit coupled to the stack, for circulating positive electrolyte through the stack; and a valve coupling the positive electrolyte circuit and the negative electrolyte circuit. The valve includes a closed configuration that prevents flow of electrolyte between the positive electrolyte circuit and the negative electrolyte circuit, and an open configuration that enables flow of electrolyte from at least one of the positive electrolyte circuit and the negative electrolyte circuit to the other of the positive electrolyte circuit and the negative electrolyte circuit. The valve is opened and closed by changes in pressure differences between the positive and the negative electrolyte circuits.
