The negative electrode, or anode, is where the reduction reaction takes place during the discharge of the battery. It serves as the destination for the electrons generated by the positive electrode. The reaction at the negative electrode allows the battery to maintain a balanced electrochemical system.
During normal use of a rechargeable battery, the potential of the positive electrode, in both discharge and recharge, remains greater than the potential of the negative electrode. On the other hand, the role of each electrode is switched during the discharge/charge cycle. During discharge the positive is a cathode, the negative is an anode.
During discharge, the positive electrode is a cathode, and the negative electrode is an anode. During charge, the positive electrode is an anode, and the negative electrode is a cathode. An oxidation reaction is an electrochemical reaction that produces electrons.
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. Cathode – the positive electrode, at which electrochemical reduction takes place.
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.
A cathode is an electrode where a reduction reaction occurs (gain of electrons for the electroactive species). In a battery, on the same electrode, both reactions can occur, whether the battery is discharging or charging. When naming the electrodes, it is better to refer to the positive electrode and the negative electrode.
