Luigi Galvani Presents Electrical Basis On The Battery
Luigi Galvani demonstrated what we now understand to be the electrical basis of nerve impulses and provided the cornerstone of research for later inventors like Volta to create batteries. Galvani was working in his frog lab when he accidentally touched two different medaled tools and created an electric nerve impulse within the frogs dead nerves. -
Alessandro Volta Voltaic Pile
Alessandro Volta invented the Voltaic Pile and discovered the first practical method of generating electricity. Constructed of alternating discs of zinc and copper with pieces of cardboard soaked in brine between the metals, the Voltic Pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. Alessandro Volta's voltaic pile was the first "wet cell battery" that produced a reliable, steady current of electricity. -
The Grove Cell
The Grove cell was invented by Welshman William Robert Grove in 1839. It consisted of a zinc anode dipped in sulfuric acid and a platinum cathode dipped in nitric acid, separated by porous earthenware. The Grove cell provided a high current and nearly twice the voltage of the Daniell cell, which made it the favoured cell of the American telegraph networks for a time. -
The First Alkaline Battery
A Swedish scientist named Waldemar Jungner invented the nickel–cadmium battery, a rechargeable battery that had nickel and cadmium electrodes in a potassium hydroxide solution; the first battery to use an alkaline electrolyte.
