In electrochemistry we study the conversion of electrical energy to chemical and chemical energy to electrical energy.
If we place two metal strips in an electrolyte, based on their electrode potential values, one of the metal strip will act as anode and other as cathode. The anode will undergo oxidation and cathode will undergo reduction. This can be like we pass electric current and electrolysis occurs or due to migration of electron electric current is produced. Both the cases will be studied in electrochemistry.
