Button battery, as a small, lightweight and easy to carry power source, is widely used in various small electronic devices. Its unique size and performance make it an ideal choice for many portable devices. This article will explore the working principle, types, application fields and market development trends of button batteries in depth.
1. Working principle of button battery
The working principle of button battery is similar to other types of batteries, all of which are based on electrochemical reactions to generate electricity. The battery contains key components such as positive electrode, negative electrode and electrolyte. When the battery is connected to an external circuit, a chemical reaction occurs between the positive and negative electrodes, releasing electrons and flowing through the external circuit to generate electricity.
2. Types of button batteries
Button batteries can be divided into many types according to their chemical composition and structure. Among them, common types include alkaline manganese batteries, lithium batteries and silver oxide batteries. These different types of button batteries have differences in performance, capacity and service life, so they are suitable for different application scenarios.
Alkaline manganese battery: This battery has a high energy density and a long service life, and is suitable for devices that need to be powered for a long time, such as electronic thermometers, remote controls, etc.
Lithium battery: Lithium battery has higher energy density and more stable voltage output, and is suitable for devices that require high energy output and stable voltage, such as smart wearable devices, RFID tags, etc.
Silver oxide battery: Silver oxide battery has a smaller volume and higher operating voltage, and is suitable for devices that require small volume and high voltage, such as hearing aids, watches, etc.
3. Application fields of button batteries
Button batteries have a wide range of applications, covering almost all devices that require small and lightweight power supplies. The following are some of the main application areas:
Portable electronic devices: Such as remote controls, calculators, electronic watches, etc., these devices usually require small and lightweight power supplies to power them.
