Because of the safety issues of lithium ion batteries (LIBs) and considering the cost, they are unable to meet the growing demand for energy storage. Therefore, finding alternatives to LIBs has become a hot topic. As is well known, halogens (fluorine, chlorine, bromine, iodine) have high theoretical specific capacity, especially
Only three systems as such have seen some commercial development, namely the all-vanadium (by VRB-ESS), the bromine–polysulfide (RGN-ESS) and the zinc–bromine (Powercell) systems.
