In ancient times, human beings may have been constantly researching and testing such things as electricity. But there are several different theories about who invented the first battery.
The Italian Alessandro Volta is usually attributed to the honor of the inventor of the modern battery (Silver-Zinc). Anicent cells have been found in the ruins of the Sumerian as early as 250 BC. The first evidence comes from archaeological excavations in Baghdad, Iraq. This first battery is dated to the year 250 BC. The vessel was found in Khujut Rabu outside Baghdad and consists of clay vessels wrapped in a copper cylinder. When filled with vinegar or any other electrolyte, the vessel produces about 1.1 volts! The battery was used for electrical galvanizing ie. provide different objects with a thin layer of metal, a method similar to the ones we use today for plating cheap gold and silver objects. Luigi Galvani was the first to make an electrochemical cell in 1798, after which Di Volta (after whose name Volt was named) a few years later succeeded in constructing a so-called. primary cell ie a cell that cannot be charged. In parallel with Di Volta, J-W Ritter worked in the years 1776-1810 with a rechargeable secondary cell also called accumulator. G Planté has since 1859 made a lead accumulator, an accumulator that basically exists even now.
In 1860, France’s George Leclanche also invented the predecessor of the world’s most widely used battery (carbon zinc battery). Its negative electrode is an alloy rod of zinc and mercury (the anode of a zinc-volt prototype battery, which has proven to be one of the best metals for making negative electrodes), and its positive electrode is a porous cup containing crushed two A mixture of manganese oxide and carbon. A carbon rod was inserted into the mixture as a current collector. Both the negative electrode rod and the positive electrode cup are immersed in an ammonium chloride solution as an electrolyte. This system is called “wet battery”. Although the battery made by Lakeland was simple but cheap, it was not replaced by an improved “dry cell” until 1880. The negative electrode is modified into a zinc can (ie, the battery case), and the electrolyte becomes a paste instead of a liquid. Basically this is what we now know as a carbon zinc battery.
In 1887, the Englishman Hellerson invented the earliest dry cell. The electrolyte of the dry battery is pasty, does not leak, and is easy to carry, so it is widely used.
In 1890 Thomas Edison invented the rechargeable iron-nickel battery.
