Flow cell with corrugated flow screen

1. A flow cell comprising:

a housing defining anode and cathode cavities each configured to permit electrolyte flow therethrough;

an anode disposed within the anode cavity;

an ion conductive membrane separating the cavities; and

an electrically conductive flow screen having a corrugated form, being in contact with the anode, and arranged within the anode cavity such that the flow screen is configured to provide an electric shield to limit metal plating between the flow screen and anode during charge, and peaks of the flow screen adjacent to the membrane are configured to provide preferential metal plating areas relative to valleys of the flow screen to promote deposition of metal on the peaks during charge.

2. The flow cell of claim 1 , wherein a distance between the peaks of the flow screen and the membrane is less than a distance between the peaks of the flow screen and the anode.

3. The flow cell of claim 1 , wherein the peaks of the flow screen adjacent to the membrane are configured to provide preferential metal plating areas relative to the valleys of the flow screen such that a strength of the electric shield increases as metal plating on the flow screen increases.

4. The flow cell of claim 1 , wherein the flow screen is metal.

5. The flow cell of claim 4 , wherein the flow screen is an expanded metal, a perforated metal, or a woven mesh.

6. A flow cell comprising:

a separator and anode arranged to define a flow chamber configured to direct an electrolyte therethrough; and

an electrically conductive corrugated flow screen, in contact with the anode, having peak portions proximate the separator configured to provide preferential metal plating areas relative to valleys of the flow screen to promote deposition of metal on the peak portions between the flow screen and separator during charge to form an electric shield that hinders deposition of metal between the flow screen and anode.

7. The flow cell of claim 6 , wherein a distance between the peak portions and the separator is less than a distance between the peak portions and the anode.

8. The flow cell of claim 6 , wherein a strength of the electric shield increases as deposition of metal between the flow screen and separator increases.

9. The flow cell of claim 6 , wherein the flow screen is metal.

10. The flow cell of claim 9 , wherein the flow screen is an expanded metal, a perforated metal, or a woven mesh.

11. A battery comprising:

a flow cell including a separator and anode defining a flow cavity, and an electrically conductive corrugated flow screen disposed within the cavity and electrically connected with the anode such that peaks of the flow screen, during charge, are configured to provide preferential metal plating areas relative to valleys of the flow screen to promote deposition of metal on the peaks between the separator and flow screen to form an electric shield to hinder deposition of metal between the anode and flow screen.

12. The battery of claim 11 , wherein a distance between the peaks and the separator is less than a distance between the peaks and the anode.

13. The battery of claim 11 , wherein a strength of the electric shield increases as deposition of metal between the separator and flow screen increases.

14. The battery of claim 11 , wherein the flow screen is metal.

15. The battery of claim 14 , wherein the flow screen is an expanded metal, a perforated metal, or a woven mesh.
