Description
Technical Field
The utility model relates to the technical field of vanadium redox batteries, in particular to a system for improving the operation efficiency of an all-vanadium redox flow battery.
Background
The proportion of new energy and renewable energy is getting larger and larger. Because the new energy and the renewable energy have volatility and intermittence, a corresponding energy storage system is required to be equipped for reducing the influence on a power grid and stabilizing the system. The all-vanadium redox flow battery is a long-period energy storage system with large scale and safe use. The vanadium redox flow battery energy storage system is developed as a chemical battery energy storage system for grid-level energy storage application, has the advantages of simple management, good single body consistency, safe operation, independent design of power and capacity, long service life and the like, and has wide application prospects in the fields of new energy access, smart grid construction and the like.
The all-vanadium redox flow battery realizes the storage and release of electric energy through the conversion of vanadium ions with different valence states through a proton exchange membrane. Electrolyte solutions of different valence states are respectively stored in different electrolyte tanks. The circulation of the electrolyte in the tank is achieved by a pump. The electrolytes with different valence states flow through the electrode surface in parallel and undergo electrochemical reaction, and released electrons are collected by the bipolar plate. Thereby realizing the conversion of chemical energy stored in electrolytes with different valence states into electric energy. The charging and discharging of all-vanadium redox flow batteries are two reversible processes. In the charging process, tetravalent vanadium ions in the positive electrode electrolyte are converted into pentavalent vanadium ions, trivalent vanadium ions in the negative electrode electrolyte are converted into divalent vanadium ions, in the discharging process, pentavalent vanadium ions in the positive electrode electrolyte are converted into tetravalent vanadium ions, divalent vanadium ions in the negative electrode electrolyte are converted into trivalent vanadium ions, and the inside of the battery is electrically conductive through H+. The V (V) and V (iv) ions exist as VO 2 + ions and VO 2+ ions, respectively, in an acidic solution, so the positive and negative reactions of the vanadium cell can be expressed as follows:
Positive electrode during charging: VO 2 ++H2O→VO2++2H+ +e-
Negative electrode during charging: v 3++e-→V2+
Positive electrode during discharge: VO 2 ++2H++e-→VO2++H2 O
Negative electrode during discharge: v 2+→V3+ + e-
In the charging process, tetravalent vanadium ions in the positive electrode electrolyte are converted into pentavalent vanadium ions, and as the charging process is carried out, the concentration of tetravalent vanadium ions in the positive electrode electrolyte in the storage tank gradually becomes smaller, and the concentration of pentavalent vanadium ions gradually becomes larger. Meanwhile, in the cathode storage tank, trivalent vanadium ions are converted into divalent vanadium ions, and as the charging process is carried out, the concentration of the trivalent vanadium ions in the cathode electrolyte in the storage tank gradually becomes smaller, and the concentration of the divalent vanadium ions gradually becomes larger. As the concentration of vanadium ions in the tank changes, the charging process speed becomes smaller. Thereby extending the time and efficiency of charging.
However, certain defects exist in the charging process, and in the charging and discharging processes of the all-vanadium redox flow battery system, electrolyte is a vanadium ion multivalent state system and is an active substance for electrochemical reaction in the all-vanadium redox flow battery, so that energy storage and release are realized. As the charging process or the discharging process proceeds, the concentration of ions of a certain valence state in the storage tank may change. If the 5-valent vanadium ions in the anode storage tank are reduced in the charging process, the concentration of the 5-valent vanadium ions in the whole tank is reduced, and the charging efficiency is affected.
