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 …
