The advantages of flow batteries include easy scalability and long cycle life. Among its disadvantages are relatively low energy density and high component cost.
Form Energy’s use of sulfur, which is both cheap and abundant, lowers those costs dramatically.
As described in PV-Magazine, the battery uses sulfur in the anode and aerated liquid salt in the cathode. Oxygen flowing in and out of the cathode makes the battery discharge and charge.
