Do batteries have atoms

Yes batteries are a form of electricity know as DC or Direct Current. Direct current is produced by such sources as batteries ,thermocouple's cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric charge flows in a constant direction, distinguishing it from alternating current or AC.
