An electric battery is a gadget consisting of one or more electrochemical cells with external connections supplied to power electric devices such as for example flashlights, smartphones, and electric cars. Whenever a electric battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the resource of electrons that whenever connected to an exterior circuit will flow and deliver energy to an external device. Whenever a battery is connected to an exterior circuit, electrolytes are able to move as ions within, allowing the chemical substance reactions to be completed at the different terminals and so deliver energy to the external circuit. It’s the movement of those ions within the electric battery that allows current to stream from the battery to perform work. Historically the term “battery” specifically described a device made up of multiple cells, however the use has evolved additionally to include devices composed of a single cell.
Primary (single-make use of or “disposable”) batteries are used once and discarded; the electrode components are irreversibly changed during discharge. Common examples are the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the initial composition of the electrodes could be restored by invert current. For example the lead-acid batteries found in vehicles and lithium-ion batteries used for portable electronics such as for example laptops and smartphones.

According to a 2005 estimate, the worldwide electric battery industry generates All of us$48 billion in sales each year, with 6% annual growth.
Batteries have lower particular energy (energy per device mass) than common fuels such as for example gasoline. In automobiles, that is somewhat offset by the bigger efficiency of electric motors in making mechanical work, in comparison to combustion engines.
