This membrane also prevents electrical shorting through the electrolyte. Lead acid batteries store energy by the reversible chemical reaction shown below. The overall chemical reaction is: P b O 2 + P b + 2 H 2 S O 4 ⇔ c h a r g e d i s c h a r g e 2 P b S O 4 + 2 H 2 O. At the negative terminal the charge and discharge reactions are:
Lead–acid battery principles. The overall discharge reaction in a lead–acid battery is: (1)PbO2+Pb+2H2SO4→2PbSO4+2H2O. The nominal cell voltage is relatively high at 2.05 V. The positive active material is highly porous lead dioxide and the negative active material is finely divided lead.
In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A. Furthermore, if the battery is a 12V ...
Lithium-ion batteries charge substantially faster than lead-acid batteries. For example, if a lead-acid battery requires eight hours to charge, a lithium-ion battery with the same capacity will most likely charge in less than two hours.
