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, 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.
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
Anode and Cathode The electrode of a battery that releases electrons during discharge is called anode; the electrode that absorbs the electrons is the cathode. 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.
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.
The cathode of a battery is positive and the anode is negative. Tables 2a, b, c and d summarize the composition of lead-, nickel- and lithium-based secondary batteries, including primary alkaline. Lead turns into lead sulfate at the negative electrode, electrons driven from positive plate to negative plate. Table 2a: Composition of lead acid.
