Abstract

The invention discloses a pteridine aqueous organic redox flow battery. According to the pteridine aqueous organic redox flow battery, organic molecules containing a pteridine structure is taken as a negative electrode; potassium ferrocyanide, TEMPO or benzoquinone potassium sulfonate is taken as a positive electrode; one or a mixture of more of an acid solution, an alkali solution and a salt water solution is taken as an electrolyte; a perfluorosulfonic acid-polytetrafluoroethylene copolymer membrane is taken as an ion exchange diaphragm; two copper plates serve as a current collector of the battery; a graphite plate with a flow channel is used as a flow field plate of the positive electrode and the negative electrode; a carbon paper, graphite felt or a metal electrode serves as an electrode of the battery; and the pteridine aqueous organic redox flow battery has the advantages of power energy design flexibility, low cost, large-scale assembly and application and the like, and is very suitable for large-scale energy storage application.

Description

Technical field

[0001] The invention belongs to the field of large-scale energy storage, and particularly relates to a pteridine-based aqueous organic redox flow battery. Background technique

[0002] Since the first industrial revolution, the consumption of fossil energy such as oil, coal and other non-renewable resources has increased year by year, which has brought about an increasingly severe energy crisis. At the same time, the sulfides, nitrogen oxides and greenhouse gases contained in them have brought harm to the earth. Environmental damage and the greenhouse effect have become crises that people have to face. The utilization and collection of clean renewable resources such as wind, tidal and solar energy are seen as a solution to this problem. However, the intermittency and spatiotemporal uncertainty of these energy sources as well as the huge fluctuations in current peaks and valleys have a negative impact on the grid. The impact has hindered the further developme...
