An anode is one of two electrodes in a battery where oxidation occurs during electrochemical reactions. In simpler terms, it is the site where electrons leave the battery and flow into the external circuit. The charge of the anode can be either positive or negative, depending on the type of battery and its state of operation.

Guide to Battery Anode, Cathode, Positive, Negative

Cathodes and Anodes are electrodes of any battery or electrochemical cell. These help in the flow of electrical charges inside the battery. Moreover, the cathode has a positive charge, where reduction occurs (receives electrons). In contrast, the anode has a negative charge, where oxidation occurs (loss of electrons) and electricity is produced.

6 FAQs about [Battery positive or negative electrode materials]

What is the difference between a positive and a negative electrode?

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. The positive electrode is the electrode with a higher potential than the negative electrode.

What is the difference between a positive and a negative battery?

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.

Is a cathode a positive or negative electrode?

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.

Is a battery anode positive or negative?

The battery anode is always negative and the cathode positive. This appears to violate the convention as the anode is the terminal into which current flows. A vacuum tube, diode or a battery on charge follows this order; however taking power away from a battery on discharge turns the anode negative.

What is a negative electrode in a lead-acid battery?

In lead-acid batteries, the anode is negative during discharge. The sponge lead (Pb) acts as this electrode, while lead dioxide (PbO2) is the cathode. The oxidation reaction at the anode can be expressed as: Pb + SO₄²⁻ → PbSO₄ + 2e⁻ This indicates that lead loses electrons (is oxidized), confirming its role as a negative electrode.

What is a negative electrode in a battery?

When discharging, it acts as a negative electrode. Lead-Acid Batteries: Lead dioxide (PbO2) is the positive terminal during discharge, while sponge lead (Pb) is the negative terminal. Each type of battery has its unique chemistry that influences how it operates, and its components interact.
