3. What Is The Chemistry Of A Car Battery?

The battery needs to have a different chemical base that varies according to the battery type.

For example, a Nickel-Cadmium car battery would have Nickel and Cadmium for longer life, temperature range, and high discharge rate. A Zinc-Carbon car battery contains manganese dioxide as a cathode, zinc as anode and zinc chloride or ammonium chloride as an electrolyte.

On the other hand, Lead-Acid batteries carry lead dioxide and metallic lead as an anode and sulfuric acid (electrolyte). The Lithium-Ion battery uses various substances, but the best combination is that of carbon as an anode and lithium cobalt as a cathode.

Lastly, the Reusable Alkaline battery has an anode, which is a zinc powder, and a cathode made from manganese dioxide mixture. The battery has got its name from potassium hydroxide electrolyte, a soluble substance.
