What is the “reverse polarity” of a battery?
The chemical reaction equation of a lead-acid battery says: PbO2+2H2SO4+Pb=PbSO4+2H2O+PbSO4 It can be seen from the reaction equation that PbSO4 is generated on the positive and negative plates after the discharge is completed. At this time, theoretically speaking, if the same substance is immersed in the electrolyte, there is naturally no potential difference, and there …
