The zinc electrode is common to both zinc/chlorine and zinc/bromine flow batteries. Although considerable progress has been made in engineering these batteries, there are still problems with the zinc electrode. The objective of this work is to elucidate the mechanism of zinc deposition in acid electrolytes and to devise methods to control zinc electrode morphology. In this subcontract, work focused on obtaining baseline data in ultra pure zinc chloride and zinc bromide electrolytes. Emphasis was on the initial stages of electrocrystallization. In addition, the effect of modified charging methods, organic surfactants, inorganic additives and substrates was investigated.
