Batteries are composed of at least one electrochemical cell which is used for the storage and generation of electricity. Though a variety of electrochemical cells exist, batteries generally consist of at least one voltaic cell. Voltaic cells are also sometimes referred to as galvanic cells.

In both voltaic and electrolytic cells, oxidation occurs at the anode, while reduction occurs at the cathode. Thus, both these cells exhibit redox reactions. In both these cells, electrons flow from the anode to the cathode through the externally connected conductor.

The major difference is the presence or absence of external energy source. In an electrolytic cell, one does not need an outside source of energy like a battery while in a voltaic cell the reaction occurs simultaneously, or without help.

Electrolytic cell, any device in which electrical energy is converted to chemical energy, or vice versa. Such a cell typically consists of two metallic or electronic conductors (electrodes) held apart from each other and in contact with an electrolyte (q.v.), usually a dissolved or fused ionic compound.

Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminium and other chemicals. Electroplating (e.g., of copper, silver, nickel or chromium) is done using an electrolytic cell.

Electrochemical cells convert chemical energy into electrical energy or vice versa. Electrolytic cell is a type of electrochemical cell in which electrical energy is converted into chemical energy. Electrolytic cells consist of positively charged anode and a negatively charged cathode.

relating to the way electricity goes through a substance, usually a liquid, or the separation of a substance into its parts when electricity goes through it: Pure copper is refined from the solution through an electrolytic process. Make sure the electrolytic capacitors are connected the correct way.

The process of electrolytic refining is used to purify impure metals. In this process, the impure metal is made anode and a thin strip of pure metal is made cathode. A solution of the salt of the metal, which is to be refined is used as an electrolyte.

adjective. pertaining to or derived by electrolysis. pertaining to an electrolyte.
