The effects of the presence of additives like lead and tungstate ions in flowing alkaline zincate solutions on suppressing spongy zinc electrogrowth were examined.The results show that the two additives with optimal concentrations in flowing electrolytes can suppress spongy zinc initiation and propagation.And,the two additives can bring about uniform and compact deposits and,thereby,reduce spongy growth.The influence of lead and tungstate ions on zinc deposition/dissolution was evaluated by cyclic voltammetry.It is also shown that the addition of the two additives is largely a blocking action,and the co-deposition of lead and zinc ions may occur.The performance of the zinc-air flow battery with zinc regeneration electrolysis was determined.It shows that by the addition of 0.6M Na2WO4 or 10-4~10-3M lead,compact or mixed compact-spongy zinc deposits are created and the favorable charge/discharge performance of the battery is achieved.
