An electric battery pack is a gadget consisting of one or more electrochemical cells with external connections offered to power electric devices such as flashlights, smartphones, and electric cars. Whenever a battery is supplying electric power, its positive terminal may be the cathode and its own negative terminal may be the anode. The terminal marked negative may be the source of electrons that whenever connected to an external circuit will flow and deliver energy to an exterior device. Whenever a battery is connected to an external circuit, electrolytes have the ability to move as ions within, allowing the chemical reactions to be finished at the distinct terminals therefore deliver energy to the exterior circuit. It’s the movement of these ions within the electric battery that allows current to flow out from the battery to perform function. Historically the word “battery” specifically described a device made up of multiple cells, however the usage has evolved to include devices composed of a single cell additionally.
Primary (single-make use of or “disposable”) batteries are utilized once and discarded; the electrode materials are irreversibly transformed during discharge. Common examples will be the alkaline battery used for flashlights and a variety of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an used electric current; the original composition of the electrodes could be restored by invert current. Examples include the lead-acid batteries found in vehicles and lithium-ion batteries used for portable electronics such as laptops and smartphones.

According to a 2005 estimate, the worldwide electric battery industry generates US$48 billion in sales every year, with 6% annual growth.
Batteries have lower specific energy (energy per unit mass) than common fuels such as for example gasoline. In automobiles, this is relatively offset by the higher efficiency of electrical motors in producing mechanical work, compared to combustion engines.
