Common Types of Batteries LAB (Lead Acid Battery) History The lead acid battery was first discovered and invented by a French physicist called Gaston Plante in 1859. The lead acid battery was the first type of battery that was rechargeable. Source Used: http://lead-acid.com/lead-acid-battery-history.shtml Plante first model for the rechargeable lead acid battery consisted of two lead sheets that have been rolled up and separated by a flannel. This is then placed in to a dilute (10%) sulphuric acid solution. http://www.electrical4u.com/working-of-lead-acid-battery-lead-acid-secondary-storage-battery/ Construction of a Lead Acid Battery Source Used: http://chemwiki.ucdavis.edu/Analytical_Chemistry/Electrochemistry/Case_Studies/Commercial_Galvanic_Cells Inside a standard lead …show more content…

At this time, the materials were so expensive compared to other battery types available. The Nickel-Cadmium was only limited to special applications. In 1947 research was carried out on a sealed nickel-cadmium battery. Source Used: http://www.batteryfacts.co.uk/BatteryHistory/Jungner.html Constructions of a Ni-Cad Battery The anode of a Ni-Cad battery consists of a Nickel Oxyhydroxide (NiO(OH) material and a cathode consisting of Cadmium Hydroxide (CdOH). These are both separated by separators which are made out of Nylon. The electrolyte in a Ni-Cad battery is made up of Potassium Hydroxide (KOH). Source Used: http://chemwiki.ucdavis.edu/ Charging of a Ni-Cad Battery During the charging process the cathode loses oxygen and turns into metallic cadmium. The nickel oxyhydroxide (NiO(OH) in the anode becomes oxidized. This process continues while during the charging process until all the oxygen

    Just like many other scientific discoveries, the discovery and isolation of lithium was a group effort. In 1817, a Swedish scientist by the name of Johan Arfwedson was the first person to discover Lithium. While doing an analysis on the mineral petalite in 1817, Arfwedson found this soft, silver-white element. Jons Jakob Berzelius, another Swedish chemist, named the element the Greek name “lithos.” Later on, the element’s name was then changed to lithium. Although lithium had finally been discovered, none of the aforementioned scientists were able to isolate pure lithium without it being attached to its salts. It was not until 1821 when two English chemists by the names of Sir Humphrey Davy and William Thomas Brande isolated lithium by electrolyzing lithium oxide (LiO2).

    Energy storage is a means of storing energy for future use and can be accessed when needed. Storage can also make the power more solid or resilient so that it can be managed easier. According to Lockheed Martin “The GridStar Lithium-ion system can help customers reduce electric bills, help utilities defer costly transmission and distribution infrastructure upgrades, and enable the integration of behind-the-meter customer renewable electricity production” (Corporation,

    Ewald Georg von Kleist is a German scientist who created the capacitor in November of 1745. Regrettably, Kleist did not have the proper paper work to claim in the records that the design of the capacitor was his idea. Many months later, a Dutch professor named Pieter van Musschenbroek created the Leyden jar, the world’s first capacitor (on record). It was a simple jar that was half filled with water and metal above it. A metal wire was connected to it and that wire released charges. Benjamin Franklin created his own version of the Leyden jar, the flat capacitor. This was the same experiment for the more part, but it had a flat piece of glass inside of the jar. Michael Faraday was the first scientist to apply this concept to transport electric power over a large distance. Faraday created the unit of measurement for a capacitor, called Farad.

    Batteries where the chemicals cannot be returned to their original form once the energy has been converted (that is, batteries that have been discharged) are called primary cells or voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators.

    In 1800, Volta discovered the battery by studying earlier experiments. He believed that metals that are different could create electricity when in contact with each other. In his experiment, he stacked copper, zinc and cardboard, which was soaked in salt water. When both ends of the stack were touched, electricity flowed. This was the first battery.
