The Seven Secrets You Will Never Know About Toshiba Li-Ion Battery Pack Pa100u-10Brs – Toshiba Li-Ion Battery Pack Pa3817u-1Brs
An electric battery is a device consisting of one or more electrochemical cells with exterior connections provided to power electrical devices such as for example flashlights, smartphones, and electrical 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 external device. When a battery is connected to an external circuit, electrolytes have the ability to move as ions within, allowing the chemical substance reactions to be finished at the individual terminals and so deliver energy to the external circuit. It is the movement of these ions within the electric battery which allows current to flow out from the battery to perform function. 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-use or “disposable”) batteries are used once and discarded; the electrode components are changed during discharge. Common examples will be the alkaline battery utilized for flashlights and a multitude of portable gadgets. Secondary (rechargeable) batteries can be discharged and recharged multiple moments using an used electric current; the initial composition of the electrodes can be restored by reverse 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 US$48 billion in sales each year, with 6% annual growth.
Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. In automobiles, that is somewhat offset by the higher efficiency of electrical motors in producing mechanical work, compared to combustion engines.
