Embodiment 1

[0045] An alkaline hydroxyphenazine organic liquid flow battery, the preparation method of which is as follows:

[0046] like Figure 1-4 As shown, the preparation of hydroxyphenazine is as follows:

[0047] Benzoquinone and its derivatives and o-phenylenediamine are reacted in a low temperature environment with absolute ethanol as a solvent for 2-12 hours. After the reaction, a large amount of water is added to filter, the filter cake is collected, and dried to obtain HP and its derivatives.

[0048]Use ammonium persulfate as a catalyst and water as a solvent to react o-phenylenediamine and its derivatives for 12-48 hours. After the reaction, add an alkali solution to filter, collect the filtrate, and adjust the pH of the filtrate so that the AHP and its derivatives in the filtrate are After the solid is precipitated, it is suction filtered, the filter cake is collected, and then dried to obtain AHP and its derivatives.

Embodiment 2

[0061] An alkaline hydroxyphenazine organic liquid flow battery, the preparation method of which is as follows:

[0062] Hydroxyphenazine was prepared as follows:

[0063] Benzoquinone and its derivatives and o-phenylenediamine were reacted in a low temperature environment with absolute ethanol as a solvent for 8 hours. After the reaction, a large amount of water was added to filter, the filter cake was collected, and dried to obtain HP and its derivatives.

[0064] Use ammonium persulfate as a catalyst and water as a solvent to react o-phenylenediamine and its derivatives for 24 hours. After the reaction, add an alkali solution to filter, collect the filtrate, and adjust the pH of the filtrate so that AHP and its derivatives in the filtrate are precipitated as solids. After suction filtration, the filter cake is collected, and then dried to obtain AHP and its derivatives.

Abstract

The invention discloses an alkaline hydroxyl phenazine organic flow battery and a preparation method thereof; the preparation method comprises the steps of enabling hydroxyl phenazine substituted by different functional groups to be neutralized by alkali, and then to be dissolved in an alkali solution to serve as a negative electrode electrolyte; dissolving potassium ferrocyanide in alkali to serve as a positive electrode electrolyte; and loading the positive electrode electrolyte and the negative electrode electrolyte in a positive electrode electrolyte tank and a negative electrode electrolyte tank respectively, and carrying out assembling to form a battery. According to the method, the problem that the existing negative electrode is relatively high in attenuation rate is solved.

Description

technical field [0001] The application belongs to the field of electrochemical energy storage, and relates to an alkaline hydroxyphenazine organic liquid flow battery and a preparation method thereof. Background technique [0002] At present, the energy sources used in the world are mainly thermal power plants and nuclear power plants. The output power converted by these power stations is as high as 1GW, but it still cannot meet the demand. Since the Industrial Revolution in the 19th century, fossil energy has been exploited and consumed on a large scale, making CO in the atmosphere 2 The concentration has increased from 280ppm to more than 400ppm today, and the resulting greenhouse effect has caused serious ecological problems. Nuclear power plants have a good effect on alleviating the greenhouse effect, but the nuclear waste produced is also a great test for human society. In fact, in addition to fossil energy and nuclear energy, new energy sources such as geothermal en...
