Abstract

The invention discloses a vanadium liquid flow electric pile assembling process. The process comprises the following steps: S1, assembling an electric pile unit; S2, stacking a plurality of assembledelectric pile units into an electric pile, and then pressing the electric pile; S3, assembling a sealing plate; S4, assembling a confluence nozzle; and S5, assembling clamping plates on the top surface and the bottom surface of the stack. The stack units are assembled in a laser welding mode, stacked stacks are pressed through a stack press-fitting clamp, and finally a sealing plate and a confluence nozzle are assembled in a laser welding mode. By means of the steps, the vanadium liquid flow galvanic pile can be efficiently assembled, the assembled galvanic pile has no hidden danger of liquidleakage, the quality of the galvanic pile is greatly improved, and the service life of the galvanic pile is greatly prolonged.

Description

technical field [0001] The invention relates to a process for producing a vanadium liquid flow stack. Background technique [0002] Vanadium redox flow battery is a redox battery that uses vanadium as an active material in a circulating liquid state. The electrical energy of the vanadium battery is stored in the sulfuric acid electrolyte of vanadium ions in different valence states in the form of chemical energy, and the electrolysis is hydraulically injected into the battery stack through an external pump, and under the action of mechanical power, it is stored in different liquid storage tanks and half-cells. Circulating flow in a closed circuit, the proton exchange membrane is used as the diaphragm of the battery pack, the electrolyte solution flows through the electrode surface in parallel and an electrochemical reaction occurs, and the current is collected and conducted through the double electrode plate, thereby forming the mutual conversion of electrical energy and che...
