- Zinc–bromine_battery abstract "The zinc–bromine flow battery is a type of hybrid flow battery. A solution of zinc bromide is stored in two tanks. When the battery is charged or discharged the solutions (electrolytes) are pumped through a reactor stack and back into the tanks. One tank is used to store the electrolyte for the positive electrode reactions and the other for the negative. Zinc bromine batteries from different manufacturers have energy densities ranging from 34.4–54 W·h/kg.[citation needed]The predominantly aqueous electrolyte is composed of zinc bromide salt dissolved in water. During charge, metallic zinc is plated from the electrolyte solution onto the negative electrode surfaces in the cell stacks. Bromide is converted to bromine at the positive electrode surface and is stored in a safe, chemically complexed organic phase in the electrolyte tank. Each high-density polyethylene (HDPE) cell stack has up to 60 bipolar, plastic electrodes between a pair of anode and cathode end blocks.The zinc–bromine battery can be regarded as an electroplating machine. During charging zinc is electroplated onto conductive electrodes, while at the same time bromine is formed. On discharge the reverse process occurs, the metallic zinc plated on the negative electrodes dissolves in the electrolyte and is available to be plated again at the next charge cycle. It can be left fully discharged indefinitely without damage.The primary features of the zinc bromine battery are: High energy density relative to lead–acid batteries 100% depth of discharge capability on a daily basis High cycle life of > 2,000 cycles at 100% depth of discharge, at which point the battery can be serviced to increase cycle life to over 3,500 cycles[citation needed] No shelf life limitations as zinc–bromine batteries are non-perishable, unlike lead–acid and lithium-ion batteries, for example. Scalable capacities from 10 kW·h (0.036 GJ) to over 500 kW·h (1.8 GJ) systems The ability to store energy from any electricity generating source The need to be fully discharged every few days to prevent zinc dendrites that can puncture the separator The need every 1-4 cycles to short the terminals across a low impedance shunt while running the electrolyte pump, to fully remove zinc from battery platesThree examples of zinc–bromine flow batteries are ZBB Energy Corporation's Zinc Energy Storage System (ZESS), RedFlow Limited's Zinc Bromine Module (ZBM), and Premium Power's Zinc-Flow Technology.These battery systems compete to provide energy storage solutions at a lower overall cost than other energy storage systems such as lead-acid, vanadium redox, sodium–sulfur, lithium-ion and others.".
