Toyo Engineering has filed a patent for a redox flow battery design. The battery includes a cell frame with recesses, sheet-like electrodes received in the recesses, a membrane covering the recesses, and a bipolar current collecting member connected to the electrodes. The cell frame has flow channels that allow a fluid with an active material to flow parallel to the membrane. The electrodes are positioned in the recesses at an angle where they intersect the membrane.

Redox flow battery with angled electrodes and flow channels
A recently filed patent (Publication Number: US20230197996A1) describes a new design for a redox flow battery. The battery includes a cell frame with a recess, at least one sheet-like electrode placed in the recess, and a membrane covering the recess. A bipolar current collecting member penetrates the cell frame at the recess and is electrically connected to the electrode. The cell frame also has flow channels that allow a fluid containing an active material to flow parallel to the membrane. The electrode is positioned in the recess at an angle where it intersects the membrane.
In this design, the electrode is inclined in the flow direction of the fluid with respect to a plane perpendicular to the flow direction. The electrode can be made of carbon paper, carbon cloth, or carbon felt. The bipolar current collecting member includes a bipolar portion that penetrates the cell frame and at least one sheet-like current collecting portion made of a conductive material. This current collecting portion can be disposed on one or both surfaces of the electrode and can have a porous, grid-like, or mesh-like structure.
The bipolar portion of the current collecting member is located within an opening formed in the recess. The battery may also include an electrode support between the electrode and the cell frame or within the opening to provide additional support. This electrode support can include auxiliary support plates arranged along the flow direction of the fluid and can also function as a membrane support.
The conductive material used in the current collecting portion is typically carbon. The battery can have multiple electrodes spaced apart from each other in the flow direction of the fluid.
Overall, this patent describes a redox flow battery design that incorporates various features to improve its performance and efficiency. The inclined electrode placement, use of carbon-based materials, and the presence of a bipolar current collecting member contribute to the battery's functionality. The design also allows for easy flow of the fluid containing the active material, enhancing the battery's overall performance.
