    摘要： An all-vanadium redox flow battery and an operation method thereof, which belong to the field of flow batteries. The all-vanadium redox flow battery comprises a positive electrolyte and a negative electrolyte. A total vanadium ratio of the positive electrolyte and the negative electrolyte is maintained at the following ratio: positive electrolyte: negative electrolyte =1:1.5-1:1.2. Both the positive electrolyte and negative electrolyte comprise additives, the concentration of the additives being 0.01mol/L-0.5mol/L. the additive is at least one selected from sulfuric acid, sulfate, phosphoric acid, phosphate, pyrophosphate, and polyphosphate. The all-vanadium redox flow battery can operate with high-energy-density, and can also significantly reduce the irreversible discharge capacity attenuation caused by a hydrogen evolution side-reaction.

    摘要： An electrode structure of a flow battery, a flow battery stack, and a sealing structure of the flow battery stack, wherein the density of the vertical tow in the electrode fiber is larger than the density of the parallel tow. In the electrode fiber per unit volume, the quantity ratio of the vertical tow to the parallel tow is at least 6:4. The electrode structure is composed of an odd number of layers of the electrode fibers, and the porosity of other layers is larger than the porosity of the center layer. The electrode structure is mainly composed of the vertical tows perpendicular to the surface of the electrode, so that, firstly, the contact area between the outer surface of the electrode and the adjacent component can be increased and the contact resistance can be reduced, secondly, the electrode is endowed with good mechanical properties, compared with the original structure, the contact resistance of such structure is reduced by 30%-50%; and the layers of the electrode have different thickness depending on the porosity, after compression, the layers with optimized thickness have a consistent porosity, this compressed uniform structure avoids uneven mass transfer phenomena when the electrolyte flows through the electrode, and reduces the concentration polarization of the battery and thereby improving the battery energy output under the given power.
