The biggest change in chemistry is an alteration to the chemical mix in the electrolyte that makes it more alkaline (what did you expect?). This change helps to increase storage density and shelf life of the cells.

The construction (as opposed to chemistry) of alkaline cells differs significantly from ordinary carbon-zinc cells, however. Alkaline cells are effectively turned inside-out. The shell of the alkaline battery is nothing more than that–a protective shell–and it does not play a part in the overall chemical reaction. The anode of the cell is a gelled mixture of powered zinc combined with the electrolyte (itself a mixture of potassium hydroxide–a strong alkaline-and water), and the combination is linked to the negative terminal of the cell by a brass spike running up the middle of the cell. The cathode, a mixture of carbon and manganese dioxide, surrounds the anode and electrolyte, separated by a layer of non-woven fabric such as polyester. The figure below illustrates the construction of a Duracell alkaline battery.

Car batteries are normally the lead-acid type provide a nominal 12-volt potential difference by connecting six galvanic cells in series. Since the cells naturally produce about 2.1 V, the actual voltage is roughly 12.6 V. Lead-acid batteries are made up of plates of lead and lead oxide, which are submerged into an electrolyte solution of about 35% sulfuric acid and 65% water. This causes a chemical reaction that releases electrons, allowing them to flow through conductors to produce electricity.
