Where are battery electrodes located?
The electrodes are located on the positive and negative sides of the battery, known as the terminals or poles. The positive electrode, also called the cathode, is where the oxidation reaction occurs during the discharge of the battery. It acts as the source of electrons, releasing them into the external circuit.
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.
What is an electrode in a battery cell?
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.
Which electrode is negative when charging a lithium ion battery?
In lithium-ion batteries, the anode is also negative when discharging. The primary material used for this electrode is graphite. Lithium ions move from cathode to anode during charging and intercalate into graphite layers. The reaction at the anode can be represented as: Li⁺ + e⁻ + C → LiC₆
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.
Are the positive and negative electrodes of a battery the same?
No, the positive and negative electrodes of a battery are specific parts of the internal structure. The positive electrode is typically made of a metal oxide, while the negative electrode is made of a metal or carbon material. These electrodes are not accessible from the outside of the battery and cannot be used as terminals.
