battery

Physics

A number of electric cells joined together. The common car battery, or accumulator, usually consists of six secondary cells connected in series to give a total e.m.f. of 12 volts. A torch battery is usually a dry version of the Leclanché cell, two of which are often connected in series. Batteries may also have cells connected in parallel, in which case they have the same e.m.f. as a single cell, but their capacity is increased, i.e. they will provide more total charge. The capacity of a battery is usually specified in ampere-hours, the ability to supply 1 A for 1 hr, or the equivalent.

Chemical Engineering

An electric cell used to produce electrical energy. Archaeologists claim that there is evidence from c.200 bc Bagdad of batteries being used in early electroplating. Italian physicist Count Alessandro Volta (1745–1827) developed a battery in 1796 that was the first primary source of electrical energy in the form of direct current (DC). His ‘voltaic pile’ consisted of stacked silver and zinc plates in an acid electrolyte, and could deliver a useful amount of power over a period of several minutes. However, it was not possible to recharge it. French physicist Georges Leclanché (1839–82) developed a carbon-zinc battery in 1866, which was later developed to produce a dry cell battery that is still used today. Rechargeable batteries were first constructed in 1866 by French physicist R. L. Gaston Planté (1834–89) and offered a more convenient electrical source by allowing the electrochemical reaction to be reused and the electrical energy to be replenished. The most common rechargeable battery is the lead-acid battery used in conventional cars.

Electronics and Electrical Engineering

A source of direct current or voltage that consists of two or more electrolytic cells connected together and used as a single unit.
A floating battery is formed from secondary cells and is connected simultaneously to a discharging circuit and a charging circuit. The current in the charging circuit is adjusted so as to balance the loss of charge from the battery to the discharging circuit driven by it. A constant level of charge is therefore maintained in the battery. A floating battery is often used to provide a constant e.m.f. in the discharge circuit, despite fluctuations in the electrical mains supply.
A dry battery is a relatively small portable battery made up from dry cells that can be discharged once. Rechargeable batteries can be discharged and recharged many times.
