SODIUM-BASED HYBRID FLOW BATTERIES WITH ULTRAHIGH ENERGY DENSITIES

摘要

A sodium-based hybrid flow battery characterized by ultrahigh energy density includes a flow cathode, a non-flow sodium-based anode spaced apart from the flow cathode and with a solid non-porous ion exchange membrane disposed between the flow cathode and the anode. The flow cathode is in fluid flow communication with a source of a catholyte material. In operation, flow of the catholyte material in the flow cathode and diffusion of sodium ions through the non-porous ion exchange membrane produce electrical energy. Also provided are corresponding or associated methods of producing electrical energy.
