WebJul 6, 2024 · Even without looking into electrochemistry details, energy conservation law requires doubled voltage for 2 identical cells in a serie. In fact, such voltage doubling has nothing to do with electrochemistry. Remember that electrolyte in cells has it electrostatic potential, and that thede potentials differ between cells by the cell voltage.
