Vanadium redox flow batteries. Christian Doetsch, Jens Burfeind, in Storing Energy (Second Edition), 2022. 7.4.1 Zinc-bromine flow battery. The zinc-bromine flow battery is a so-called hybrid flow battery because only the catholyte is a liquid and the anode is plated zinc. The zinc-bromine flow battery was developed by Exxon in the early 1970s. The zinc is plated during the charge
Bromine is a highly toxic material and the corrosive nature of the electrolyte of a zinc-bromine flow battery requires components that can handle the aggressive environment. Vanadium itself is an expensive material and flow batteries containing vanadium can have up to 43% of their cost just in the vanadium materials.
