Embodiment Construction

[0016] In this context, the term "selectively" means that a switching valve communicates two different components through position switching. For example, the expression "valve A is interposed between components B and C, and selectively communicates to component D" means that any two of components A, B, and C can be selectively connected between any two of components A, B, and C through valve A. Make sure that there is at least one bit that connects A and B, and one that connects A and C.

[0017] In a first aspect of the present invention, an electrolysis system for preparing battery fluid for a vanadium battery is provided. figure 1 A schematic diagram of a typical embodiment of an electrolysis system according to the invention is shown. In this embodiment, the electrolysis device includes three-stage electrolytic cells connected in series, the first electrolytic cell D1 is a primary electrolytic cell, the second electrolytic cell D2 is a secondary electrolytic cell, and th...

Abstract

The invention relates to an electrolytic system for preparing a vanadium cell fluid, and the electrolytic system comprises a first electrolytic tank (D1), a second electrolytic tank (D2) and a third electrolytic tank (D3) all of which are connected in series orderly, and further comprises a first valve switching valve (F1) which is arranged between the second electrolytic tank (D2) and the third electrolytic tank (D3) and selectively communicated to the inlet (E1) of the first electrolytic tank (D1) and a first reservoir (G+ / -), a second valve switching valve (F2) which is arranged between the first electrolytic tank (D1) and the second electrolytic tank (D2) and selectively communicated to the inlet (E1) of the first electrolytic tank (D1), a third valve switching valve (F3) which is arranged between a second reservoir (G0) and the inlet (E1) of the first electrolytic tank (D1), and a fourth valve switching valve (F4) which is arranged between the first reservoir (G+ / -) and the inlet (E1) of the first electrolytic tank (D1). The outlet of the third electrolytic tank (D3) is communicated to the inlet of the first electrolytic tank (D1). The invention further relates to an electrolytic method. The device provided by the invention is capable of preparing the electrolyte through continuous electrolysis, improving the electrolytic rate and preparing the electrolytes of different states of charge simultaneously according to requirements.

Description

technical field [0001] The invention relates to a method for preparing vanadium battery liquid, and also relates to a preparation device for vanadium battery liquid. Background technique [0002] All-vanadium redox flow battery is a new type of electric energy storage device. Its advantages are that the output power and energy storage capacity of the battery system are independent of each other, and the system design is flexible; the energy efficiency is high, up to 70-80%; Up to 100 MWh; the reliability of the battery is high, and the deep discharge can reach more than 90%; the startup is rapid; the location of the system is free, not subject to geographical restrictions; most of the battery components and materials can be recycled, showing a large cost advantage ; The construction period is short, and the system operation and maintenance costs are low; especially, it has the advantages of safe operation and environmental friendliness. [0003] Due to its outstanding advan...
