Electrode
An electrode is the electrical part of a cell and consists of a backing metallic sheet with active material printed on the surface. In a battery cell we have two electrodes: Anode – the negative or reducing electrode that releases electrons to the external circuit and oxidizes during and electrochemical reaction.
What is an Electrode? (with pictures)
Electrodes are used in arc welding, a technique for joining two pieces of metal using a large electric current. A consumable electrode melts, and provides the material that joins the metals. The non-consumable type is made from a material with a very high melting point, such as tungsten, and simply provides the heat to melt another …

DOE Explains...Batteries | Department of Energy
Similarly, for batteries to work, electricity must be converted into a chemical potential form before it can be readily stored. Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit.
