Zinc-carbon battery: The zinc-carbon chemistry is common in many inexpensive AAA, AA, C and D dry cell batteries. 2  The anode is zinc, the cathode is manganese dioxide, and the electrolyte is ammonium chloride or zinc chloride. 3  Alkaline battery: This chemistry is also common in AA, C and D dry cell batteries.
Rating Newest Oldest. Best Answer: The battery is a chemical power house. the plates are made of lead (Pb) and Lead Oxide (PbO) the acid is H2SO4 sulphuric acid. A charged battery has only H2SO4 (sulphuric acid) and lead plates Pb. As you use the battery, a chemical reaction occurs. Pb + HSo4 -> PbSO4 + H + freeing 2 electrons.
