Effects of recharging strategy for zinc-air battery
View through CrossRef
This research presents recharging strategies for zinc-air battery to study its recharging performance including recharging time, efficiency and cycling stability resulted from oxygen evolution reaction and water electrolysis reaction which is side reaction. The effects of recharging current density on these reactions are studied. In addition, various recharging strategies are also investigated to improve recharging performances of the battery. The results are obtained through simulation in Matlab. It was found that recharging with high current density resulted in incomplete of recharging process due to oxygen bubbles growth from high rate of oxygen evolution. This problem can be overcome by two-stage and multi-stage recharging strategies which yield 100% state of charge (SOC) of the battery with high efficiency in short time. Furthermore, the cycling stability of the battery is improved by these strategies. As for the effects of side reaction, it affects insignificantly small scale battery.
