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.
In a commercial battery, the electrodes are often made from zinc and manganese oxide. These electrodes are separated by the electrolyte - usually in the form of a paste or a liquid. When the battery is wired up in a circuit, an electrochemical reaction takes place.
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.
Here’s an illustration: In a battery, the anode refers to the negative electrode of a primary cell that releases electrons into the external circuit. This happens through the oxidation process. However, if the battery is rechargeable, the anode becomes the positive electrode during recharging.
Conversely, the cathode in a battery refers to the positive electrode receiving the electrons that flow from the anode. This is where the reduction reaction occurs when the battery is being used. If the battery is rechargeable, this electrode becomes the anode when the battery is being recharged. What is the Conventional Cell Representation?
For a discharging battery, the electrode at which the oxidation reaction occurs is called the anode and by definition has a positive voltage, and the electrode at which the reduction reaction occurs is the cathode and is at a negative voltage.
