6 FAQs about [Influence of sulfuric acid concentration on lead-acid batteries]
What is the molar concentration of sulfuric acid in a battery?
The concentration of sulfuric acid in a fully charged auto battery measures a specific gravity of 1.265 – 1.285. This is equivalent to a molar concentration of 4.5 – 6.0 M. 2,3 The cell potential (open circuit potential or battery voltage, OCV) is a result of the electrochemical reactions occurring at the cell electrode interfaces.
Does sulfuric acid concentration affect negative plate performance?
The influence of sulfuric acid concentration on negative plate performance has been studied on 12 V/32 Ah lead-acid batteries with three negative and four positive plates per cell, i.e. the negative active material limits battery capacity.
How does acid concentration affect battery charge efficiency?
Batteries with electrolyte concentrations within the H-region exhibit higher charge efficiency, which decreases slightly with increase of C H 2 S O 4. In the N-region of acid concentrations, the charge efficiency decreases substantially with increase of acid concentration for both discharge rates.
Does a high H2SO4 concentration affect the cycle life of lead-acid batteries?
The observed influence of H 2 SO 4 concentration on the behaviour of lead-acid batteries and the clear distinction between the two types of LAB imply that, most probably, it is the high H 2 SO 4 concentration in VRLAB that limits the cycle life performance of these batteries.
Does acid concentration affect battery cycle life?
Batteries with high SoC exhibit high charge acceptance at low acid concentrations. The cycle life tests at two discharge rates (10 and 3 h discharge) evidence that sulfuric acid concentration exerts a strong effect on negative plate performance. The cycle life of batteries decreases with increase of acid concentration.
What happens if H2SO4 concentration decreases during battery discharge?
During battery discharge, the H 2 SO 4 concentration decreases. If the H 2 SO 4 concentration in the batteries decreases to 1.10–1.11 g cm −3 at the end of discharge, this corresponds to the region of maximum solubility of PbSO 4 (see Fig. 10 ).
