Transition metal compounds serve as the cathode materials in Zn-M batteries and function as the active components of bifunctional catalysts in ZABs.

Do all zinc-based flow batteries have high energy density?

Indeed, not all zinc-based flow batteries have high energy density because of the limited solubility of redox couples in catholyte. In addition to the energy density, the low cost of zinc-based flow batteries and electrolyte cost in particular provides them a very competitive capital cost.

What are zinc-bromine flow batteries?

Among the above-mentioned zinc-based flow batteries, the zinc-bromine flow batteries are one of the few batteries in which the anolyte and catholyte are completely consistent. This avoids the cross-contamination of the electrolyte and makes the regeneration of electrolytes simple.
