An electric battery is a device that consists of one or more electrochemical cells that convert stored
chemical energy into electrical energy.Each battery consists of a negative electrode that holds charged
ions, a positive electrode that holds discharged ions, an electrolyte that allows ions to move from anode to
cathode during discharge and terminals that allow current to flow out of the battery to perform work.
Batteries are either primary that are used once and discarded or secondary that are discharged and
recharged multiple times.
Batteries are made from many materials including various metals, carbon, polymers and even air. The most
common are lead-acid batteries used in vehicles and lithium ion batteries used for portable electronics.
Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches
to battery banks the size of rooms that provide standby power for telephone exchanges and computer
data centers.
Batteries have recently received significant research and development, because they are seen as essential
in the transition from fossil fuels to alternative energy, both for transport and electricity production and
for powering portable devices of all kinds.
