Zinc–bromine rechargeable batteries (ZBRBs) are one of the most powerful candidates for
next-generation energy storage due to their potentially lower material cost, deep discharge
capability, non-flammable electrolytes, relatively long lifetime and good reversibility.
However, many opportunities remain to improve the efficiency and stability of these batteries
for long-life operation. Here, we discuss the device configurations, working mechanisms and
performance evaluation of ZBRBs. Both non-flow (static) and flow-type cells are highlighted …
