Batteries are stores of energy created by the interaction of different elements at the atomic level. Since the first battery was invented in 1799 using only copper and zinc, researchers have harnessed many other elements, each with its unique properties, for use in batteries. Some elements, like lithium and nickel, can be used to make many types of batteries. Others like, vanadium and cadmium, are, as of today, only used in one type of battery each. And the vast majority of e
