An electrochemical cell is a device that either generates electrical energy from chemical reactions in a so called galvanic or voltaic cell, or induces chemical reactions (electrolysis) by applying external electrical energy in an electrolytic cell.[1][2]
Both galvanic and electrolytic cells can be thought of as having two half-cells: consisting of separate oxidation and reduction reactions.
When one or more electrochemical cells are connected in parallel or series they make a battery. Primary battery consists of single-use galvanic cells. Rechargeable batteries are built from secondary cells that use reversible reactions and can operate as galvanic cells (while providing energy) or electrolytic cells (while charging).
