CR1220 Button Cell Battery Type
Button batteries are also divided into two categories: chemical batteries and physical batteries, and their chemical battery applications are the most common. They consist of an anode (positive electrode), a cathode (negative electrode), and their electrolytes. As shown on the right. Its appearance is stainless steel, and as a positive electrode, its negative electrode is a round stainless steel cover, there is a seal ring insulation between the positive and negative, the seal ring is made of nylon, the seal ring in addition to the insulation, but also to prevent electrolyte leakage . There are many types of button batteries, most of which are named after the materials used, such as silver oxide batteries, lithium batteries, and alkaline manganese batteries.
Button Cell Batteries
Button cell (button cell) is also called a button cell. It refers to a battery with a small button size. Generally, it has a larger diameter and a thinner thickness (as opposed to a columnar battery such as the No. 5 AA on the market). Button batteries are based on the appearance of the battery points, the equivalent corresponding battery classification columnar batteries, square batteries, special-shaped batteries.
It is a secondary button battery and a button battery that can be charged and discharged many times; nominal voltage: 3.7V; charging voltage 4.2V
The corresponding mark can be seen from the back of the battery
