Zinc-bromine (ZnBr) flow batteries can be categorized as hybrid flow batteries, which means that some of the energy is stored in the electrolyte and some of the energy is stored on the anode by plating it with zinc metal during charging. In a ZnBr battery, two aqueous electrolytes act as the electrodes of the battery and store charge.
