  • Patent number: 10593982
    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.

  • Patent number: 9842706
    Abstract: Disclosed are a method of manufacturing a flexible thin-film type super-capacitor device and a super-capacitor device manufactured by the same. The flexible thin-film type super-capacitor device comprises a base film which has flexibility; a separator which is interposed between the base films; and an active material which is formed on the base film. Thus, flexibility is given since thickness is very thin while maintaining high electrical conductivity and high binding property. In addition, economic feasibility is high and mass production is possible. Further, it is possible to stably and efficiently contain a highly corrosive material.

  • Patent number: 9761379
    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.
