Abstract

The invention provides a flow cell stack, comprising two endplates, a diaphragm, and two bipolar plates, the flow cell stack is separated into an anode electrolyte area and a cathode electrolyte areathrough the diaphragm between the two endplates, each area is provided with a bipolar plate which has the same polarity with the electrolyte of the corresponding area and the same polarity at both sides; two poles of the same bipolar plate are connected in parallel; an inlet of each bipolar plate is arranged at the same position below the bipolar plate, and an outlet of each bipolar plate is arranged at the same position above the bipolar plate. The flow cell stack is simple in structure, can reduce the requirement on the performance of the material of the bipolar plate effectively, particularly the requirement on the compactness of the bipolar plate so as to reduce the production cost effectively; meanwhile, the flow cell stack can effectively decrease the self-discharging and reduction of efficiency of the cell caused by the crossing between the anode electrolyte and the cathode electrolyte in the cell stack and prolong the service life of the cell, is suitable to be an update of theprior flow cell stack, particularly to be used on a cell stack which needs large current discharging.

Description

technical field

[0001] The invention relates to a liquid flow battery, in particular to a liquid flow battery stack structure, and belongs to the fields of energy storage and electrochemistry. Background technique

[0002] Since the energy of the flow battery is stored in the electrolyte, the battery capacity can be increased by increasing the volume of the liquid storage tank or increasing the concentration of the solution; the stack is separated from the active material, and the battery power and capacity can be adjusted separately; the charging and discharging process Does not include complex multi-phase reactions, and does not have active material shedding and short-circuit phenomena that often occur in general battery systems; deep charging and discharging have little effect on battery life; the status of each unit battery in the battery pack is basically the same, and maintenance is simple and convenient; By replacing the electrolyte to achieve the purpose of fast char...
