6.10.1: Lead/acid batteries
Chemistry The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4 + H + + 2e – At the cathode: PbO 2 + 3H + + HSO 4 – + 2e – → PbSO 4 + 2H 2 O ...

The main tasks of automotive lead-acid batteries are to ensure the cranking of the internal combustion ... In Fig. 4, a top view of an AGM LN5 battery (95 Ah) after such a discharge procedure is shown. The …
Discharge and Charging of Lead-Acid Battery
When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte. The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation.
Why don''t lead acid batteries last forever?
If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. ...

NiMH batteries do the opposite - they get hot while charging, but cool themselves during discharge. The other factor that must be taken into account is temperature. A 10°C increase can double the activity of ions in an electrolyte, which will cause its resistance to drop dramatically.

How Does Lead-Acid Batteries Work?
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
