A device containing two conducting electrodes, one positive and the other negative, made of dissimilar materials (usually metals) that are immersed in a chemical solution (electrolyte) that transmits positive ions from the negative to the positive electrode and thus forms an electrical charge. one or more cells constitute a battery.

Experimental methods used to study the physical and chemical phenomena associated with electron transfer at the interface of an electrode and a solution. electrochemical methods are used to obtain analytical or fundamental information regarding electroactive species in solution. four main types of electrochemical methods include potentiometry, voltammetry, coulometry, and conductimetry.
The characteristics of materials that occur when a) an electric current is passed through a material and produces chemical changes and b) when a chemical reaction is used to produce an electric current, as in a battery.
