REDOX FLOW BATTERY(RFB) USING ELECTROLYTE CONCENTRATION GRADIENT AND OPERATION METHOD THEREOF

摘要

The present invention relates to a redox flow battery using an electrolyte concentration gradient and a method for operating the same, and more specifically, to a redox flow battery using an electrolyte concentration gradient capable of increasing the efficiency of the redox flow battery and its operating method. It is about. To this end, the redox flow battery includes an electrolyte inlet at the top, an electrolyte outlet at the bottom, and an anode electrolyte tank having a partition wall installed in a vertical direction to form a concentration gradient of the anode electrolyte accommodated therein; A cathode electrolyte tank having an electrolyte inlet at the top, an electrolyte outlet at the bottom, and a partition wall installed in a vertical direction to form a concentration gradient of the cathode electrolyte accommodated therein; And a stack unit receiving and supplying the electrolyte from the anode electrolyte tank and the cathode electrolyte tank to store and discharge power.
