Semi-solid redox flow battery

materials used in Li-ion batteries and the design and functioning of a redox flow cell. The use of Li-ion battery materials offers significant increases in energy and power density (200 Wh/kg compared to 25-35 Wh/kg for current commercial vanadium redox batteries). The implementation of a redox flow system allows for energy to be stored outside the cell and for the power and energy of the battery to be decoupled. A proof of concept is achieved by successful cycling of anode and cathode suspensions under intermittent flow conditions. The importance of materials' stability to cell life, energy and power densities is discussed. The high energy densities may enable the use of the proposed system in a variety of application, ranging from grid-level storage to fully electric charge.
