Abstract

The invention relates to the field of a vanadium cell, and particularly relates to a liquid flow frame device for the vanadium cell, and the vanadium cell containing the liquid flow frame device, which can be used for overcoming the defects of low leakage resistance, reliability and stability and the like in a liquid flow frame of the prior art and the defect of low reliability of the traditional vanadium cell. A liquid flow frame which is provided with passageways, liquid openings and liquid holes is adopted in the liquid flow frame device, wherein the liquid openings refer to a liquid inlet opening and a liquid outlet opening; the liquid holes refer to a liquid inlet hole and a liquid outlet hole; a sheet frame I and a sheet frame II are arranged at the two sides of the liquid flow frame in parallel, a rotary liquid flow passageway I and a rotary liquid flow passageway II are respectively arranged on the sheet frame I and the sheet frame II, a structure is centrally and symmetrically arranged between the rotary liquid flow passageway I and a rotary liquid flow passageway II, each rotary liquid flow passageway is an arch passageway which is bended and rotary more than two times, and the arch passageways are distributed at the two sides of the liquid flow frame. The liquid flow frame device provided by the invention has better reliability, stability and higher efficiency. The vanadium cell has high reliability, efficiency and stability.

Description

technical field [0001] The invention relates to the field of vanadium batteries, in particular to a flow frame device for the vanadium battery and a vanadium battery containing the flow frame device. Background technique [0002] The vanadium battery is called the full vanadium redox flow battery (Vanadium Redox Battery, abbreviated as VRB), which is a redox battery energy storage system based on the metal vanadium element. 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, using the proton exchange membrane as the diaphragm of the battery pack, the electrolyte solution flows in parallel across the electrode surface and undergo...
