A zinc–bromine battery is a rechargeable battery system that uses the reaction between zinc metal and bromine to produce electric current, with an electrolyte composed of an aqueous solution of zinc bromide. It is being developed as an alternative to lithium-ion batteries for stationary power applications, from domestic to grid-scale. The water-based electrolyte makes the battery system less prone to overheating and fire compared with lithium-ion battery systems. WebThe model is based on the Zn]Br,~ redox couple and can be used as an aid for the design of an efficient rechargeable storage battery. It is shown that four independent variables exist for the system at a fixed temperature: the effective separator thickness, the residence time, the channel width, and the potential driving force. ...
