The electrolyte solution in a lead-acid battery consists of approximately 35% sulfuric acid and 65% water. The acid concentration is usually between 4.2-5 mol/L, and the solution has a density of 1.25-1.28 kg/L. The electrolyte solution plays a vital role in the battery’s operation.
Sulfuric acid is a crucial component of lead-acid batteries. It is used as an electrolyte, which facilitates the chemical reaction that produces electrons. The acid concentration in the electrolyte solution is essential to the battery’s performance. If the concentration is too low, the battery may not produce enough power.
The acid concentration is usually between 4.2-5 mol/L, and the solution has a density of 1.25-1.28 kg/L. The electrolyte solution plays a vital role in the battery’s operation. When the battery is charged, the acid reacts with the battery plates to produce lead sulfate and hydrogen ions.
A lead-acid battery has two types of electrodes: a lead dioxide (PbO 2) positive electrode (or cathode) and a lead (Pb) negative electrode (or anode). The battery acid is the electrolyte that allow for ion movement between the electrodes. This type of battery is rechargeable.
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.
In a functional lead-acid battery, the ratio of acid to water should remain close to 35:65. You can use a hydrometer to analyze the precise ratio. In optimal conditions, a lead-acid battery should have anywhere between 4.8 M to 5.3 M sulfuric acid concentration for every liter of water. How do you properly refill a battery with acid?
