What is the working principle of lead-acid battery charging and discharging?

source:Industry News release time:2024-03-11 Hits:     Popular:AG11 battery

  

  We take the lead-acid battery as an electrochemical reaction system, which is:

  PbO2 H2SO4 Pb

  Positive electrolyte negative electrode

  The battery reacts as follows during charging and discharging:

  PbO2+2H2SO4+Pb = PbSO4+2H2O+PbSO4

  It can be seen from the results of the reaction that both the positive and negative electrodes generate lead sulfate after work. It is not difficult to see that the product of this discharge reaction is the bipolar formation of lead sulfate.

  Negative electrode: Pb+H2SO4-2e-→PbSO4+2H+

  Positive electrode: PbO2+H2SO4+2H++2e-→PbSO4+2H2O

  The two electrons lost from the negative electrode flow to the positive electrode through the external circuit. After the lead dioxide on the positive electrode obtains two electrons from the external circuit, the Pb4+ ion becomes the Pb2+ ion.
