A dry cell is a type of battery that is commonly used in household devices such as flashlights, radios, and portable electronic devices. It is called a dry cell because it does not contain a liquid electrolyte, which makes it suitable for use in portable devices that may be tilted or turned upside down. The main advantage of a dry cell is that it can be used in any position, as the lack of a liquid electrolyte means that it will not leak.
A lithium battery, on the other hand, is a type of rechargeable battery that uses lithium ions as the main charge carrier. Lithium batteries are known for their high energy density, which means that they can store a large amount of energy in a small package. They are commonly used in portable electronic devices such as laptops and smartphones, as well as in electric vehicles and other high-energy applications.
In general, lithium batteries are more expensive than dry cells and may not be as widely available. However, they offer a number of advantages over dry cells, including a longer shelf life, a higher energy density, and the ability to be recharged.
