Impact of Acetate Additive on PbO2 Plating and Oxygen Evolution in Soluble lead flow Batteries Soluble lead flow batteries (SLFBs), a potential form of large-scale energy storage, are currently facing the challenge of short cycle life. #SLFBresearch We aim to elucidate the effect of acetate additive on SLFBs. We find that the mechanical strength of the PbO2 layer plated by acetate-assisted electrolyte is materially enhanced. These further discoveries are of critical value for
