What is an electrode in a battery cell?
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 a positive electrode in a battery?
electrode A conductor used to establish electrical contact with a circuit. The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. The electrode attached to the positive terminal of a battery is the positive electrode, or anode.
What is a negative electrode in a battery called?
The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. The electrode attached to the positive terminal of a battery is the positive electrode, or anode. A substance which, when molten or in solution, will conduct an electric current.
