Chemical Batteries

An chemical battery may be a device consisting of 1 or a lot of chemistry cells with external connections provided to power electrical devices like flashlights, smartphones, and electrical cars. once battery is provision power, its positive terminal is that the cathode and its negative terminal is that the anode. The terminal marked negative is that the supply of electrons that once connected to Associate in Nursing external circuit can flow Associate in Nursing deliver energy to an external device. once battery is connected to Associate in Nursing external circuit, electrolytes square measure ready to move as ions at intervals, permitting the chemical reactions to be completed at the separate terminals so deliver energy to the external circuit. it's the movement of these ions at intervals the battery that permits current to emanate of the battery to perform work. traditionally the term "battery" specifically observed a tool composed of multiple cells, but the usage has evolved to boot to incorporate devices composed of one cell.
