An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode …
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources.
What is a battery? Batteries power our lives by transforming energy from one type to another. Whether a traditional disposable battery (e.g., AA) or a rechargeable lithium-ion battery (used in cell phones, laptops, and cars), a battery stores chemical energy and releases electrical energy.
Batteries power the appliances you use daily. Check out battery experiments, the history of batteries, battery reactions and the chemistry behind battery power.
battery, in electricity and electrochemistry, any of a class of devices that convert chemical energy directly into electrical energy. Although the term battery, in strict usage, designates an assembly of two or more galvanic cells capable of such energy conversion, it is commonly applied to a single cell of this kind.

Batteries are a collection of one or more cells whose chemical reactions create a flow of electrons in a circuit. All batteries are made up of three basic components: an anode (the ''-'' side), a cathode (the ''+'' side), and some kind of electrolyte (a substance that chemically reacts with the anode and cathode).
noun. bat· tery ˈba-t (ə-)rē. plural batteries. Synonyms of battery. 1. a. : the act of beating someone or something with successive blows : the act of battering (see batter entry 1 sense 1) b. law : an offensive touching or use of force on a person without the person''s consent. evidence that supports a charge of battery.
Science Made Simple: What Are Batteries and How Do They Work?
Batteries were invented in 1800, but their chemical processes are complex. Scientists are using new tools to better understand the electrical and chemical processes in batteries to produce a new generation of highly efficient, electrical energy storage.
