▎ 摘　　要

NOVELTY - Composite bipolar plate of liquid flow battery comprises a conductive region (1) in the middle of the composite bipolar plate, and an insulating region is opened on the edge of the middle. A transition region (2) is provided between the conductive area and the insulating area (3), and the transition region communicates with the conductivity area. The transition area is connected with the insulation area. A conductive ring is pressed against the insulated area by the conductial ring. The insulating ring is press-pressed against the transition area by an outer ring. USE - Composite bipolar plate of liquid flow battery. ADVANTAGE - The liquid flow battery composite bipolar plate has good conductivity, corrosion resistance weldability, and high tightness. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing the structure of a composite bipolar plate. Conductive region (1) Transition region (2) Insulation area (3)
