Electric battery common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting chemical energy to mechanical work, compared to combustion engines. The usage of "battery" to describe a group of electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of cannon (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together). Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800. This was a stack of copper and zinc plates, separated by
Volta Prize the first practical electric motor used in industry. One of its most notable awards was made in 1880, when Alexander Graham Bell received the fourth edition of the Volta Prize for the invention of the telephone. Among the committee members who judged were Victor Hugo and Alexandre Dumas, fils. Since Bell was himself becoming more affluent, he used the prize money to create institutions in and around Washington, D.C., including the prestigious Volta Laboratory Association in 1880 (also known as the" 'Volta Laboratory' "and as the" 'Alexander Graham Bell Laboratory"') precursor to Bell Labs, with his endowment fund (the" 'Volta
