Title:
BATTERY BODY UNIT FOR REDOX FLOW BATTERY, REDOX FLOW BATTERY USING SAME, AND METHOD FOR OPERATING REDOX FLOW BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/117308
Kind Code:
A1
Abstract:
This battery body unit 10 for a redox flow battery performs charging and discharging by circulating an electrolytic solution in which an active material is dissolved to a battery cell 3 comprising an electrode 1 containing nanomaterial, an ion exchange membrane 2, and a bipolar plate. The battery body unit 10 for the redox flow battery comprises an outer frame body 4, and the following which are installed inside the outer frame body 4: the battery cell 3; internal pipes that circulate the electrolytic solution to the battery cell 4 (internal electrolytic solution outward path pipes 5, internal electrolytic solution return path pipes 6); and electrolytic solution exchange members 7 forming a portion of the path of the internal pipes. The electrolytic solution exchange members 7 have a connection part 7a that connects to an external electrolytic solution outward path pipe 12 and a connection part 7b that connects to an external electrolytic solution return path pipe 13. The connection part 7b that connects to the external electrolytic solution return path pipe 13 is provided with a filter member 8 that does not allow nanomaterial to pass through, thus establishing a sealed system for the nanomaterial that prevents the nanomaterial from flowing out of the battery body unit 10.
