Coin Cell Battery Concept, types, function, application
April 14, 2023
Coin cell battery is a small, round, flat battery that is commonly used in small electronic devices such as calculators, watches, and remote controls. It is also known as a button cell battery because of its shape.
Types:
1. Zinc-carbon (Zn-C)
2. Alkaline (AG)
3. Lithium (Li)
Function:
The coin cell battery works by converting chemical energy into electrical energy. The battery consists of two electrodes, an anode, and a cathode, separated by an electrolyte. When the battery is connected to a circuit, the chemical reaction between the anode and the electrolyte produces electrons that flow through the circuit, powering the device.
Application:
Coin cell batteries are commonly used in small electronic devices that require a low amount of power, such as calculators, watches, and remote controls. They are also used in medical devices such as pacemakers and hearing aids, as well as in automotive applications such as key fobs and tire pressure monitoring systems. Additionally, they are used in backup power supplies for computer memory and real-time clock systems.
