Under static electricity, this transfer rapidly reaches dynamic equilibrium. Open circuit voltage The terminal voltage of the battery in open circuit is the open circuit voltage, which is also the difference of the electrode potential between the two poles, but not the equilibrium potential, but the difference between the stable potential or the mixed potential. In theory, the open circuit voltage of a battery is not equal to electromotive force, but it may be near to the numerical value. The electromotive force of the electromotive force of a lead-acid battery is a function of the concentration of sulfuric acid. The open circuit voltage is also a function of sulfuric acid concentration. The relation between the open circuit voltage of the cell and the electrolyte density can be calculated in the lower form: Open circuit voltage =d+0.85 In D, at the temperature of the battery electrolyte, the density of the electrolyte (g/cm3) Establishment of stable potential Dynamic equilibrium between electrode metal ions and metal ions in solution Me - 2e Me2+ It is only an ideal condition, such as the establishment of the above equilibrium electrode potential. In fact, in aqueous electrolyte solution on the electrode, not only there is a pair of metal oxide and metal ion reduction reaction, there is also the oxidatio
