Embodiment 1
[0025] This embodiment discloses a kind of mixed acid (HCl+H 2 SO 4 ) The capacity recovery agent for the electrolyte solution of the all-vanadium redox flow battery comprises organic molecule spheres with a density lower than that of the electrolyte solution, and the organic molecules are polymerized organic molecules. The particle size of the organic molecular sphere is 8-10mm. The density of the organic molecular sphere is lower than that of the electrolyte, and it floats above the liquid surface of the electrolyte, which will not affect the normal circulation of the electrolyte, and will not block the inlet and outlet pipes of the electrolyte.
[0026] The organic molecular sphere is a double-layer structure, such as figure 1 As shown, the outer layer 1 is sodium alginate, and the inner layer 2 is embedded solid oxalic acid. The dosage ratio of the outer layer to the inner layer is 7:3 (mass ratio). The organic molecular sphere of the present invention adopts a double-...
Embodiment 2
[0032] This embodiment discloses an electrolyte capacity recovery agent for an all-vanadium redox flow battery, which includes organic molecule spheres with a density lower than that of the electrolyte, and the organic molecules are polymerized organic molecules. The particle size of the organic molecule sphere is 1-10mm. The density of the organic molecular sphere is lower than that of the electrolyte, and it floats above the liquid surface of the electrolyte, which will not affect the normal circulation of the electrolyte, and will not block the inlet and outlet pipes of the electrolyte. The organic molecule sphere has a double-layer structure, the outer layer is methyl cellulose, and the inner layer is embedded glycerin. The dosage ratio of the outer layer to the inner layer is 7:3.
