1. Introduction. A promising solution for a low cost electrical storage has recently been developed by Pletcher et al. which consists of a redox flow battery involving a highly soluble form of lead(II) (Pb(CH 3 SO 3) 2) dissolved in an aqueous methanesulfonic acid (MSA: CH 3 SO 3 H) electrolyte. Such a reactor consists, in the simplest design proposed by its authors in a …
Figure 1d displays the effect of different sulfidation ratios on TC abatement in the S-nZVI/PAA process. It can be seen that the maximum TC removal efficiency of 100% can be obtained for the S/Fe molar ratio of 0.04 and 0.07. However, the TC removal efficiency significantly decreases to 79.9% and 51.2% with the increase of the S/Fe molar ratio to 0.21 …

Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.
