Abstract: A static and closed solution casting process comprises the following steps: dissolve a solute in a solvent to prepare a casting solution; place membrane-casting plate on bracket, and adjust the bracket to make the membrane-casting plate horizontal; pour the casting solution into membrane-casting plate such that the casting solution is uniformly spread out in the membrane-casting plate; arrange heating arrangement over the membrane-casting plate; arrange cooling side plate around the membrane-casting plate; arrange cooling bottom plate below the membrane-casting plate; supply cooling liquor to the connected interlayer of the cooling side plate and the cooling bottom plate; enclose the membrane-casting plate, the bracket, the heating arrangement, the cooling side plate and the cooling bottom plate inside an insulated case made by heat insulator; heat the casting solution in the membrane-casting plate by driving the heating arrangement to totally evaporate the solvent in the casting solution; and then continuous

Abstract: Enclosed is an electrode for a flow battery, which comprises a graphite felt (1), wherein: said graphite felt includes multiple flow channels (2) for transmitting an electrolyte, said flow channels (2) are straight and distributed at equally spaced intervals, and the width and depth of said channels (2) and the interval between adjacent flow channels (2) are each half of the thickness of the graphite felt (1), which is a polyacrylonitrile graphite felt (1). Said flow battery electrolyte has a simple structure and is easily processed and assembled, the flow battery thickness and internal resistance are low, and transmission and dispersion of the electrolyte is highly effective. Flow batteries using said electrode enjoy high power density, high energy efficiency, long life, and can be made into high-power or even super-high-power flow batteries.
