OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

Despite recent advances in energy and power density, however, RFBs still require pumps—which are parasitic components and require a minium scale of operation on the order of 100s of kW to a few MWs, the OSU researchers noted. They connected batteries to an LED light, programming the holes to open and close in precise patterns.
