A controller stops flow of posolyte through a positive electrode chamber of a flow cell to trap the posolyte within the positive electrode chamber and hydraulically isolate the flow cell without stopping flow of negolyte through a negative electrode chamber of the flow cell, discharges the flow cell until hydrogen gas is evolved at a reactive surface of the positive electrode chamber while the posolyte is trapped within the positive electrode chamber, and subsequently discontinues the discharge and restarts the flow of the posolyte through the positive electrode chamber.

Flow cell decontamination

A flow cell includes a separator and anode that define a flow cavity. The flow cell also includes an electrically conductive corrugated flow screen disposed within the cavity and electrically connected with the anode such that the flow screen, during charge, provides an electric shield to hinder deposition of metal between the anode and flow screen and to promote deposition of metal between the separator and flow screen.

Flow cell with corrugated flow screen

Counter electrodes are used within the context of a flow cell to attract shunt current depositions during operation. The counter electrodes may be electrically connected with an anode of the flow cell to attract the depositions and then electrically connected with a cathode of the flow cell to remove the depositions.

Flow cell with shunt current counter electrode

An energy storage includes a cell that defines a flow chamber for receiving electrolyte, and an electrode arrangement positioned in the cell. The electrode arrangement includes a plate having first and second sides. The plate further has multiple openings that vary in size to facilitate electrolyte flow on both sides of the plate.

Perforated electrode plate

A prefabricated sacrificial galvanic anode panel includes a rigid or semi-rigid backing board or similar support surface over which a thin layer of cement, mortar or adhesive is applied for holding a compliant layer of material in place on the support surface. The layer of wet adhesive, cement or mortar is sufficiently thin so that upon drying it does not cause warping of the support surface. The compliant or spongy layer is laminated or sandwiched between a thicker layer of ionically conductive galvanic mortar and the substrate support surface. The compliant or spongy layer prevents the thicker layer of galvanic mortar from wetting the backing board or substrate support surface so as to prevent warpage upon drying of the thicker layer of galvanic mortar and also accommodates the expansion of corrosion products from the galvanic anode material.

Galvanic panel with compliant construction

A discrete sacrificial zinc anode is fabricated from one or more slotted and slatted metal plates. The plates are fixed in a parallel planar configuration using conventional fasteners. One or more electrical connection wires are formed with a looped portion for spacing the anode assembly a predetermined distance from a steel reinforcing member.

Discrete galvanic anode

An energy storage system includes a cell having a flow chamber for receiving electrolyte, and an electrode positioned in the cell. The electrode includes a base plate having a generally planar portion and a plurality of partially cutout portions partially cut out from the generally planar portion to define a plurality of openings in the base plate. Each cutout portion is attached to the generally planar portion and has a projecting part that extends away from the generally planar portion. Furthermore, the openings and the cutout portions are configured to enhance mixing of the electrolyte when the electrolyte is received in the flow chamber.

Electrode configured for turbulence

An electrolytic mortar for fabricating galvanic anode panels is strengthened with fibers to improve green strength and resistance to cracking. Elongated reinforcing fibers are introduced into a flowing stream of mortar and deposited in multiple layers upon a platen or mold. A sacrificial zinc anode of open construction is embedded between the multiple layers to allow for electrolytic conduction between the layers and over all surfaces of the zinc anode.

Spray formed galvanic anode panel

Galvanically protected reinforcement dowel pins and methods of producing the same. In one embodiment, the reinforcement dowel pins comprise a bar or tube, the longitudinal exposed surfaces of which are covered by a heavy gauge of a sacrificial metal, such as zinc, zinc alloy, magnesium, magnesium alloy, aluminum, or aluminum alloy. The bar or tube comprises steel, carbon steel, or other ferrous metal. The heavy gauge of sacrificial metal is applied to the ferrous metal by various processes, such as roll bonding, lock seaming, welding, die casting, flame spraying, plasma spraying, dipping, sinking, and drawing. The resulting reinforcement dowel pins resist corrosion without sacrificing structural integrity, and are reasonable in materials and manufacturing costs. These dowel pins may be installed in adjacent concrete panels using conventional methods, and therefore do not introduce additional costs in installation.
