Disposable Batteries are a type of voltaic battery that uses some kind of absorbent (such as wood chips or gelatin) to make the contents into a paste that does not spill out. Often used as a power source for flashlight lighting, radios, etc. Dry batteries are a type of chemical battery that uses paste electrolyte to generate direct current (wet batteries are chemical batteries using liquid electrolyte). Dry batteries are primary batteries that are commonly used in daily life and are lightweight batteries. Common dry batteries are zinc-manganese batteries.
Benefits of disposable batteries: high energy conversion rate, stable and reliable energy supply, can be made into various shapes and sizes, easy to use, easy to maintain, and can work in various environments.
Disadvantages: Keep the wax seal when not in use to prevent the water in the electrolyte from volatilizing. Also avoid high temperature and humidity. Remove the dry batteries for long-term unused appliances to prevent the electrolyte from flowing out and corrode the appliances. Pollute the environment after disposal.
Disposable Batteries are not only applicable to flashlights, semiconductor radios, radio cassette players, cameras, electronic clocks, toys, etc., but also to various fields in the national economy such as national defense, scientific research, telecommunications, navigation, aviation, and medicine.
