Universal device for reducing electrolyte migration of flow battery

The invention belongs to the field of flow battery application and energy recovery and relates to a device for reducing electrolyte migration of a flow battery, and aims to solve the problems of electrolyte migration, capacity fading and the like of an existing flow battery. According to the device, the pressures in storage tanks on the two sides are different by adjusting the pressures in electrolyte storage tanks on the two sides of a positive electrode and the negative electrode, and the migration of the electrolyte of the flow battery is reduced through the pressure difference by means of a physical mode. The migration of the electrolyte of the flow battery is reduced by adjusting the pressure in the electrolyte storage tanks on the two sides of the positive electrode and the negative electrode, meanwhile, the problems of capacity fading and the like caused by the migration of the electrolyte can be solved, and long-term operation of the battery and efficient utilization of the electrolyte are realized.
