By immersing two different metals or metal compounds (electrodes) into an ion-conducting system (electrolyte), electrons tend to move from one electrode to the other, utilizing the basic electrochemical property of the electrodes. When a load is connected, electrons start flowing from one electrode to the other, generating electricity.

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.
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
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.
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.
