Count Alessandro Volta (1745 – 1827) was born in in Como, Italy. He has been named as a legend in the electricity. The count of electricity “Volt” has been named as the Volta upon his name. The main idea came from the Luigi Galvani while he was dissecting a frog leg. The frog’s leg began to move while dissection.
Volta repeated this experiment again and again and found a relation (electric action). Later after several years he repeated this experiment again and again and found that electricity has been passing through frog leg while two electrical objects placed near to each other.
Then, Volta modified/replaced frog’s leg with other metals, tissues and physio objects and invented first wet battery known as Voltaic Pile. The voltaic pile was the first electrical battery that continuously provide an electrical current to a circuit. The original voltaic pile used zinc and silver disks and a separator consisting of a porous non-conducting material saturated with sea water. Later German researchers developed the gelled-electrolyte lead-acid battery in the early 1960’s which was a major improvement. The French emperor, Napoleon, made Volta a “Count” for his discovery. Today’s high performance gel-cell batteries are based on this principle.
