Free QuoteDuring 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.
The positive electrode has a higher potential than the negative electrode. So, when the battery discharges, the cathode acts as a positive, and the anode is negative. Is the cathode negative or positive? Similarly, during the charging of the battery, the anode is considered a positive electrode.
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.
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.
When naming the electrodes, it is better to refer to the positive electrode and the negative electrode. The positive electrode is the electrode with a higher potential than the negative electrode. During discharge, the positive electrode is a cathode, and the negative electrode is an anode.
In contrast to the anode, the cathode is a positive electrode of the battery. It gets electrons and is reduced itself. Moreover, the cathode is immersed in the battery's electrolyte solution. So, when the current is allowed to pass, the negative charges move from the anode side and reach the cathode.
