Formation of Lead-Acid Batteries and Structure of Positive and Negative

The voltage of the battery is also called electromotive force. There are two positive and negative electrodes in the battery. The electromotive force is the difference between the balanced electrode potentials of the two electrodes. Taking a lead-acid battery as an example, E=Ф+0-Ф-0+RT/F* In(αH2SO4/αH2O). Among them: E—electromotive force
