- Lead (Pb): Lead is the primary component of car battery plates. It is used because of its high electrochemical potential, which means that it can easily give up or accept electrons.
- Sulfuric Acid (H2SO4): Sulfuric acid is the electrolyte in a car battery. It is responsible for conducting the electrical current between the positive and negative plates.
- Water (H2O): Water is used to dilute the sulfuric acid in a car battery. It also helps to keep the plates cool and prevents them from overheating.
- Antimony (Sb): Antimony is an additive that is added to the lead in car battery plates. It helps to harden the plates and make them more resistant to wear.
- Calcium (Ca): Calcium is another additive that is sometimes added to car battery plates. It helps to reduce the amount of water that evaporates from the battery.
- Plastic: Plastic is used to make the case and cover of a car battery. It helps to protect the battery from damage and also prevents the electrolyte from leaking.
