Dry-cell: A dry-cell battery is a device that converts chemical energy intoelectrical energy using one or more electrochemical cells. It includes an electrolyte in the form of a paste or other moist media. A zinc anodeand acarbon cathodeare contained within a central rod in a standard dry cell battery.
Lithium-ion dry cell batteries are considered to be best for applications as they have the highestenergy density among other batteries as they are made up of lithium, which is such a light metal. Thus, they can contain an ample amount of energy as compared with any other equal-size single-use battery.
