Batteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 4 Nonetheless, it was not until 1749 that the term "battery" was coined by Benjamin Franklin to describe several capacitors (known as Leyden jars, after the town in which it was discovered), connected in series. The term "battery" was presumably chosen

Lead-acid batteries (LAB) still play an important part on the battery market, and are financially the best compromise in power, longevity and ability to be recycled in the circularity management [7, 8, 9, 10, 11, 12].
Thus, the maximum voltage reached determines the slope of the temperature rise in the lead-acid battery cell, and by a suitably chosen limiting voltage, it is possible to limit the danger of the “thermal runaway” effect.
