The electrochemistry of static lead-acid and soluble lead-acid flow batteries is summarised and the differences between the two batteries are highlighted. A general comparison of the performance of an un.
Notable exceptions include the models developed by Shah et al. 24 and by Li and Hikihara 25 for the all-vanadium system and by Scamman et al. 3 for the bromide–polysulphide battery. There are no models, as far as the authors are aware, of the soluble lead-acid flow battery, even in the simplest cases.
Self-discharge was also observed in the case of the soluble lead-acid flow battery when it was left open-circuit for a long time period. To test the self-discharge characteristic of a soluble lead-acid flow battery, a series of charge/discharge cycles were performed.
Does flow rate affect soluble lead flow battery performance?
There is little work regarding the flow rate in the soluble lead flow battery. Understanding the relationship between flow rate and cell performance is important, as this could minimise the pump power whilst maintaining good electrochemical performance.
Following a large number of charge/discharge cycles, a soluble lead-acid flow battery could fail due to cell shorting caused by the growth of lead and lead dioxide deposition the negative and positive electrode, respectively.
What is the difference between soluble and Static lead-acid battery?
Conclusions 1. The electrochemistries of the soluble lead-acid flow battery and the static lead-acid battery are distinctly different; in the soluble lead acid battery lead is highly soluble in the electrolyte of methanesulfonic acid, while lead is a solid paste in the static lead-acid battery.
The flow battery was found to have a better charge efficiency than the static one, but the cells were found to have comparable energy efficiencies. The self-discharge characteristics of the soluble lead-acid battery were also measured and compared to reported values for a commercial static battery.
