Claims

1. A metal linker, characterized in that, The system comprises three connecting plates stacked sequentially. Each connecting plate includes a first through hole, a second through hole, a third through hole, and a fourth through hole. All the first through holes are connected to form an air inlet, all the second through holes are connected to form an air outlet, all the third through holes are connected to form a gas inlet, and all the fourth through holes are connected to form a gas outlet. The three connecting plates include a first connecting plate, a second connecting plate, and a third connecting plate arranged sequentially. The first connecting plate and the third connecting plate each have a central through hole. The first through hole, the second through hole, and the central through hole on the second connecting plate form a cathode airflow channel. The third through hole, the fourth through hole, and the central through hole on the third connecting plate form an anode airflow channel. The central panel on the second connecting plate completely separates the overlapping portions of the cathode airflow channel and the anode airflow channel.

2. The metal connector of claim 1, wherein On the second connecting plate, the inner sides of the first through hole and the second through hole both extend into the central through hole located in the first connecting plate, so that the first through hole and the second through hole communicate with the central through hole on the first connecting plate. The third connecting plate is provided with a first sealing part to seal the extended portions of the first through hole and the second through hole on the second connecting plate.

3. The metal connector of claim 2, wherein On the second connecting plate, the inner sides of the third through hole and the fourth through hole both extend into the plate to the central through hole located in the third connecting plate, so that the third through hole and the fourth through hole communicate with the central through hole on the third connecting plate. The first connecting plate is provided with a second sealing part to seal the extended portions of the third through hole and the fourth through hole on the second connecting plate.

4. The metal connector of claim 3, wherein Multiple partitions are provided in the extension portions of the first through hole, the second through hole, the third through hole and the fourth through hole of the second connecting plate. The partitions can increase the connection area between the first connecting plate, the second connecting plate and the third connecting plate, and improve the connection reliability.

5. The metal connector of claim 1, wherein The first connecting plate, the second connecting plate, and the third connecting plate are all square plates with a thickness of 0.5-2mm and a side length of 180-240mm.

6. The metal connector of claim 1, wherein The central through holes on the first and third connecting plates are both rectangular holes, and the two rectangular holes are arranged in a vertical direction.

7. The metal connector of claim 1, wherein A cathode current collector is placed in the through hole in the middle of the first connecting plate to distribute airflow and current.

8. The metal connector of claim 1, wherein An anode current collector is placed in the central through hole of the third connecting plate to improve the efficiency of the electrochemical process and energy utilization.

9. The metal connector of claim 1, wherein Sealing gaskets are provided at the edges of the first through hole, the second through hole, the third through hole, the fourth through hole and the middle through hole on the outer side of the first connecting plate to prevent gas from flowing out between the single battery and the first connecting plate when the single battery is connected to the first connecting plate.

10. The metal connector of claim 1, wherein Sealing gaskets are provided at the edges of the first through hole, second through hole, third through hole, fourth through hole and the middle through hole on the outer side of the third connecting plate, so as to prevent gas from flowing out between the single cell of the adjacent battery repeating unit in the battery stack and the third connecting plate when the third connecting plate is connected to the single cell of the adjacent battery repeating unit in the battery stack.
