The non-flow zinc-bromine battery with regular porous glass fiber separator is particularly prone to low coulombic efficiency, as shown by the blank electrolyte (Figure 1 A).This is due to the serious cross-diffusion of the highly soluble Br 2 /Br 3-species, which results in direct redox reaction with the zinc anode. Although the diffusion is …
