AI Technical Summary
Existing flow batteries have low sealing stacking efficiency, poor sealing effect and high cost. They are prone to leakage due to aging of the sealing gaskets. The operation is cumbersome and requires additional equipment and manpower.
A sealing layer is formed by filling a plastic frame with liquid plastic in a flow channel. The sealing connection between the plastic frames is achieved through injection molding. The flow channel is used to accelerate the injection molding process, forming a zero-gap seal at the molecular level.
It achieves efficient and low-cost sealing, avoids the risk of leakage caused by gasket aging, improves stacking efficiency and reliability, and reduces equipment and labor costs.

Abstract
Claims
1. A sealed stack structure of a flow battery, characterized by, It includes several stacked plastic frames, each plastic frame having a flow channel filled with liquid plastic. The several plastic frames are sealed and bonded together by a sealing layer formed after the liquid plastic in the flow channel has solidified.
2. The sealed stack structure of claim 1, wherein, The guide groove is provided with a guide hole that extends through the plastic frame along the thickness direction, and the guide hole is filled with the sealing layer.
3. The sealed stack structure of claim 2, wherein, The guide holes are spaced apart within the guide groove, and the area of the guide holes accounts for 10-25% of the area of the guide groove.
4. The sealed stack structure of claim 1, wherein, The sealing layer is a rigid structure formed by curing liquid plastic of the same material as the plastic frame.
5. The sealed stack structure of claim 1, wherein, The plastic frame sealing ring is connected to the periphery of the functional component, which is a bipolar plate, an ion exchange membrane, or an electrode, and the flow channel surrounds the functional component.
6. The sealed stack structure of claim 1, wherein, The sealed stack structure also includes a liquid-passing structure.
