what is a battery

First Let me show you what’s a battery

1. Electricity.

a. Also called galvanic battery, voltaic battery. a combination of two or more cells electrically connected to work together to produce electric energy.

b. cell (def. 7a).

2. any large group or series of related things: a battery of questions.

3. Military.

a. two or more pieces of artillery used for combined action.

b. a tactical unit of artillery, usually consisting of six guns together with the artillerymen, equipment, etc., required to operate them.

c. a parapet or fortification equipped with artillery.

4. a group or series of similar articles, machines, parts, etc.

5. Baseball. the pitcher and catcher considered as a unit.

6. Navy.

a. (on a warship) a group of guns having the same caliber or used for the same purpose.

b. the whole armament of a warship.

7. Psychology. a series of tests yielding a single total score, used for measuring aptitude, intelligence, personality, etc.

8. the act of beating or battering.

9. Law. an unlawful attack upon another person by beating or wounding, or by touching in an offensive manner.

10. an instrument used in battering.

11. Also, batterie. Music. the instruments comprising the percussion section of an orchestra.

12. any imposing group of persons or things acting or directed in unison: a battery of experts.

in dictionary we have found 12 diffrent explanation

In electronics, a battery is two or more electrochemical cells connected in series which store chemical energy and make it available as electrical energy. Common usage has evolved to include a single electrical cell in the definition

One common division of batteries distinguishes two types: primary (disposable) and secondary (rechargeable).
Primary batteries are designed to be used once only because they use up their chemicals in an effectively irreversible reaction.
Secondary batteries can be recharged because the chemical reactions they use are reversible; they are recharged by running a charging current through the battery, but in the opposite direction of the discharge current.

Secondary, also called rechargeable batteries can be charged and discharged many times before wearing out. After wearing out some batteries can be recycled.

Battery History

Volta realized that the frog’s moist tissues could be replaced by cardboard soaked in salt water, and the frog’s muscular response could be replaced by another form of electrical detection. He already had studied the electrostatic phenomenon of capacitance, which required measurements of electric charge and of electrical potential. Building on this experience Volta was able to detect electric current flow through his system, now called a voltaic cell, or cell for short. The terminal voltage of a cell that is not discharging is called its electromotive force (emf), and has the same unit as electrical potential, named (voltage) and measured in volts, in honor of Volta. In 1799, Volta invented the battery by placing many voltaic cells in series, literally piling them one above the other. This Voltaic Pile gave a greatly enhanced net emf for the combination,[9] with a voltage of about 50 volts for a 32-cell pile. In many parts of Europe batteries continue to be called piles.

Unfortunately, Volta did not appreciate that the voltage was due to chemical reactions. He thought that his cells were an inexhaustible source of energy, and that the associated chemical effects (e.g. corrosion) were a mere nuisance, rather than, as Michael Faraday showed around 1830, an unavoidable consequence of their operation.

Early batteries were of great value for experimental purposes, their limitations made them impractical for large current drain. Later, starting with the Daniell cell in 1836, batteries provided more reliable currents and were adopted by industry for use in stationary devices, particularly in telegraph networks where they were the only practical source of electricity, since electrical distribution networks did not exist then.[11] These wet cells used liquid electrolytes, which were prone to leaks and spillage if not handled correctly. Many used glass jars to hold their components, which made them fragile. These characteristics made wet cells unsuitable for portable appliances. Near the end of the 19th century, the invention of dry cell batteries, which replaced liquid electrolyte with a paste made portable electrical devices practical.

The battery (Laptop Battery Camera Battery Cell Phone Battery) has since become a common power source for many household and industrial applications. According to a 2005 estimate, the worldwide battery industry generates US$48 billion in sales annually.
