Are zinc bromine flow batteries better than lithium-ion batteries?While zinc bromine flow batteries offer a plethora of benefits, they do come with certain challenges. These include lower energy density compared to lithium-ion batteries, lower round-trip efficiency, and the need for periodic full discharges to prevent the formation of zinc dendrites, which could puncture the separator.
Are zinc–bromine flow batteries good for grid-scale energy storage?Zinc–bromine flow batteries (ZBFBs) hold great promise for grid-scale energy storage owing to their high theoretical energy density and cost-effectiveness. However, conventional ZBFBs suffer from inhomogeneous zinc deposition and sluggish Br 2 /Br – redox kinetics, resulting in a short cycle life and low power density.
