Abstract: Disclosed herein is stack-type flow energy storage system. More particularly, the system includes a stack-type electrode cell composed of fluidic electrode material mixed with an electrolyte and storage tank for the electrode material, thereby remarkably improving stability, output and energy density. The stack-type flow energy storage system is advantageous in that unit cells, each consisting of a cathode, a separation membrane and an anode, are connected in parallel or in series to each other to make a stack cell, thus remarkably increasing output power. Further, the stack-type flow energy storage system is advantageous in that the sizes of slurry storage tanks connected to an electrode cell are adjusted, thus determining the required specification of energy density.

Abstract: This invention relates to an electrolyte solution for a redox flow battery containing an organic active material, in which an organic compound useful as a single active material for a cathode and an anode is dissolved in a water-soluble solvent, and to a redox flow battery using the same. The electrolyte solution of the invention is an aqueous electrolyte solution obtained by dissolving an active material in an aqueous solvent, and is thus very stable due to the low risk of fire or explosion. Furthermore, the organic compound is applied as a single active material to the cathode and the anode, and thus, when the capacity of the battery is decreased due to the permeation of the active material through the separator, the battery capacity can be restored through rebalancing.

Abstract: A method of manufacturing a graphene composite including an ultrasonic-wave pulverization post-treatment process. The method includes radiating a microwave on a mixture of graphite oxide and a conducting agent, dispersing a resultant material, obtained during the radiating the microwave, in a liquid and performing ultrasonic-wave pulverization, and freeze-drying particles subjected to the ultrasonic-wave pulverization. The post-treatment process is added to the method of manufacturing the graphene composite including the reduced graphene oxide using the graphite oxide, thereby manufacturing a graphene composite having improved bindability with spherical activated carbon used to manufacture an active material. Further, the post-treated graphene composite is used to manufacture the active material and the supercapacitor, and accordingly, the active material can be thinly and densely applied to provide a supercapacitor having improved performance.

Abstract: Disclosed is a flow-type energy storage device having an improved flow of fluid. The flow-type energy storage device stores electricity using a fluidic material, and includes a reaction region in which charge-discharge reaction of electricity is performed by the fluidic material, wherein the reaction region has an octagonal cross-section. The shape of the reaction region is controlled to thus improve the flowability of the fluidic material, thereby providing a flow-type energy storage device that has almost constant electrical properties even when a charging and discharging cycle is repeatedly performed. Further, the structures of an inlet and an outlet are not complicated and a separate part for controlling the flow of fluid is not used in the device, and accordingly, additional costs are not incurred during a process of manufacturing the flow-type energy storage device.
