Final answer:
A Duracell battery is an example of a dry voltaic cell, which is a primary, single-use, nonrechargeable battery containing a paste electrolyte.
Step-by-step explanation:
A Duracell battery is an example of a dry voltaic cell. These batteries are commonly referred to as dry cells because they contain a paste electrolyte rather than a liquid electrolyte. Furthermore, this type of battery is classified as a primary battery, which is a single-use, nonrechargeable battery. Duracell batteries, much like the Leclanché dry cell, have a zinc can that serves as the anode and a central graphite rod which acts as the cathode. The paste within contains several components including manganese (IV) oxide, zinc (II) chloride, ammonium chloride, and water. Despite the use of a moist paste, these cells are still considered 'dry' because they do not have free-flowing liquid electrolyte.
