Students and engineers developed several commercially important types of battery. "Wet cells" were open containers that held liquid electrolyte and metallic electrodes. When the electrodes were completely consumed, the wet cell was renewed by replacing the electrodes and electrolyte. Open containers are unsuitable for mobile or portable use.
Leclanché's "wet cell" (as it was popularly called) was the forerunner to the world's first widely used battery, the zinc–carbon battery. In 1876, Leclanché jellifies the electrolyte of his cell by adding starch to the ammonium chloride, making his cell more portable. [4]
A 1919 illustration of a Leclanché cell. The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. [1] [2] [3] The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).
In 1907, he became a consultant to the nearby French Battery Company (later renamed The Ray-O-Vac Company). He was charged with improvement of the French No. 6 battery [1] — the large 6-inch-tall, single-cell battery used for automobile ignition, railroad signals, telephones, doorbells and other electrical devices. Burgess was put in charge ...
Dry cell battery by Wilhelm Hellesen 1890. Many experimenters tried to immobilize the electrolyte of an electrochemical cell to make it more convenient to use. The Zamboni pile of 1812 is a high-voltage dry battery but capable of delivering only minute currents. Various experiments were made with cellulose, sawdust, spun glass, asbestos fibers ...

The entire 19th-century electrical industry was powered by batteries related to Volta's (e.g. the Daniell cell and Grove cell) until the advent of the dynamo (the electrical generator) in the 1870s. [6] Volta's invention was built on Luigi Galvani's 1780s discovery that a circuit of two metals and a frog's leg can cause the frog's leg to ...
