The first Zn/Br flow battery was patented by Bradley in 1885 [57].This was far earlier than the first modern RFB (Fe/Cr RFB). Although usually classified as a flow battery, it is different from the RFB. Generally, a Zn/Br flow battery is regarded as a hybrid RFB [58] because the active material for energy storage is not completely soluble.
