Embodiment 1
[0041] Such as figure 1 A method for manufacturing an electrolyte for a redox battery shown, the process steps are as follows:
[0042] (1) Slowly add vanadium pentoxide to the aqueous sodium hydroxide solution with a concentration of 20wt% and keep stirring, the stirring rate is controlled at 120rpm, and the addition of vanadium pentoxide is 25wt% of the quality of the alkaline aqueous solution. The speed of adding vanadium pentoxide is preferably not to produce a large amount of precipitates, and the adding time is 30 minutes;
[0043] (2) After the vanadium pentoxide addition is completed, continue to stir, and the stirring rate is controlled at 30rpm, and continues to stir for 50 minutes to make it fully dissolve;
[0044] (3) Slowly add sulfuric acid with a concentration of 25 wt% into the above system to react to generate vanadyl(IV) sulfate, stop adding when the pH value of the system reaches 2.0 to 2.2, and continue the reaction for 30 minutes;
[0045] (4) remove so...
Embodiment 2
[0052] Such as figure 1 A method for manufacturing an electrolyte for a redox battery shown, the process steps are as follows:
[0053] (1) Slowly add vanadium pentoxide to the aqueous sodium hydroxide solution with a concentration of 30wt% and keep stirring, the stirring rate is controlled at 80rpm, and the addition of vanadium pentoxide is 40wt% of the quality of the alkaline aqueous solution. The speed of adding vanadium pentoxide is advisable not to produce a large amount of precipitates, and the adding time is 60 minutes;
[0054](2) After the vanadium pentoxide addition is completed, continue to stir, and the stirring rate is controlled at 50rpm, and continues to stir for 30 minutes to make it fully dissolve;
[0055] (3) Slowly add sulfuric acid with a concentration of 20 wt% into the above system to react to generate vanadyl(IV) sulfate, stop adding when the pH value of the system reaches 2.0 to 2.2, and continue the reaction for 20 minutes;
[0056] (4) remove sodiu...
Embodiment 3
[0062] Such as figure 1 A method for manufacturing an electrolyte for a redox battery shown, the process steps are as follows:
[0063] (1) Slowly add vanadium pentoxide to the potassium hydroxide aqueous solution with a concentration of 20wt% and keep stirring, the stirring rate is controlled at 150rpm, and the addition of vanadium pentoxide is 25wt% of the potassium hydroxide aqueous solution quality. The speed of adding vanadium pentoxide is preferably not to produce a large amount of precipitates, and the adding time is 30 minutes;
[0064] (2) After the vanadium pentoxide addition is completed, continue to stir, and the stirring rate is controlled at 60rpm, and continues to stir for 30 minutes to make it fully dissolve;
[0065] (3) Slowly add sulfuric acid with a concentration of 30wt% into the above system to react to generate vanadyl(IV) sulfate, stop adding when the pH value of the system reaches 2.0 to 2.2, and continue the reaction for 30 minutes;
