Grove's 1839 gas voltaic battery diagram. In 1829, at the Royal Institution, Grove met Emma Maria Powles. [dubious – discuss].They married in 1837. The couple embarked on a tour of the continent for their honeymoon. This sabbatical offered Grove an opportunity to pursue his scientific interests and resulted in his first scientific paper [4] suggestin
Alessandro Giuseppe Antonio Anastasio Volta (UK: / ˈ v ɒ l t ə /, US: / ˈ v oʊ l t ə /; Italian: [alesˈsandro ˈvɔlta]; 18 February 1745 – 5 March 1827) was an Italian chemist and physicist who was a pioneer of electricity and power, [1] [2] [3] and is credited as the inventor of the electric battery and the discoverer of methane.
Schematic diagram of a copper–zinc voltaic pile. Each copper–zinc pair had a spacer in the middle, made of cardboard or felt soaked in salt water (the electrolyte). Volta's original piles contained an additional zinc disk at the bottom, and an additional copper disk at the top; these were later shown to be unnece
A later variant of the Daniell cell called the gravity cell or crowfoot cell was invented in the 1860s by a Frenchman named Callaud and became a popular choice for electrical telegraphy. The Daniell cell is also the historical basis for the contemporary definition of the volt , which is the unit of electromotive force in the International ...
The cell was also known as the 'chromic acid cell', but principally as the 'bichromate cell'. This latter name came from the practice of producing the chromic acid by adding sulphuric acid to potassium dichromate, even though the cell itself contains no dichromate. The Fuller cell was developed from the Poggendorff cell.
Ovshinsky was born and grew up in the industrial town of Akron, Ohio, then at the center of the American rubber industry.The elder son of working-class Lithuanian Jewish immigrant parents who left Eastern Europe around 1905—Benjamin Ovshinsky from Lithuania and Bertha Munitz from what is now Belarus—Ovshinsky became active in social activities at an early age during the Great Depression.

From his recent experimental work, Yazami theorized that in a sealed rechargeable battery cell (closed system), such as a lithium-ion battery, two different states of charge of the battery cannot simultaneously share the same entropy and the same enthalpy values, a statement referred to as the "Yazami's Battery Theorem."
His work with Cadet's fuming liquid was an important step in the development of the radical theory of organic compounds. In 1841, [ 15 ] Bunsen created the Bunsen cell battery, using a carbon electrode instead of the expensive platinum electrode used in William Robert Grove 's electrochemical cell.
