Provided are assemblies, comprising: a first leaf spring; a second leaf spring; and at least one component; the first leaf spring and the second leaf spring being superposed over a first end of the at least one component so as to exert first and second forces, respectively, through first and second regions of the component. These assemblies are useful to apply different forces to a stacked assembly where a cross section of a component of the assembly comprises materials of different Young's moduli within that cross section, thereby compressing different regions of the component with different forces.

Dual leaf spring pressure plate for a flow battery stack

The present disclosure is directed to methods for levelizing circulation rates over multiple electrochemical cells of an electrochemical cell stack due to a pressure drop that occurs at an outlet of each electrochemical cell.

Flow batteries having a pressure-balanced electrochemical cell stack and associated methods

Electrolyte solution circulation rates in a flow battery can impact operating performance. Although adjusting the circulation rates can allow improved performance to be realized, it can be difficult to levelize circulation rates over multiple electrochemical cells of an electrochemical cell stack due to a non-uniform pressure drop that occurs at an outlet of each electrochemical cell. Accordingly, flow batteries capable of realizing improved operating performance can include: an electrochemical cell stack containing a plurality of electrochemical cells in electrical communication with one another; an inlet manifold containing an inflow channel fluidically connected to an inflow side of each of the electrochemical cells; an outlet manifold containing an outflow channel fluidically connected to an outflow side of each of the electrochemical cells; and an insert disposed in the outflow channel. The insert has a variable width along a length of the outflow channel.
