1 A variety of substances are used in lithium batteries, but a common combination is a lithium cobalt oxide cathode and a carbon anode. 2  Lead-acid battery (rechargeable) : This is the chemistry used in a typical car battery. 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.
Single useâ¦ or primary batteries,  such as alkaline and zinc are the most common type of battery but  increasingly seen as wasteful and expensive in the long run. The  exact composition of the internal chemistry will vary depending on  the use the battery is designed for and the battery brand.
