Button battery (br), also known as watch battery (br) or coin battery (br), is one of the shape classifications of batteries. It refers to small batteries with shapes such as buttons, buttons, coins, beans, etc. Button-type batteries come in many styles, with diameters ranging from large to small, and thicknesses ranging from thin to thick. Most button-type batteries are primary batteries, which are also dry batteries, but they are obviously different in appearance from the common cylindrical large and long dry batteries such as AA, AA, AA, AA and AA. Shenzhen Xunjieyuan Technology specializes in the production of various types of button batteries, R,, RR,, battery cells,,,,,
Due to their small size, button batteries have been widely used in various micro electronic products. The diameter From . to 3, thickness from . to . Generally used as backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, electric toys, pacemakers, Electronic hearing aids, counters, cameras, etc. Button batteries are also divided into two categories: chemical batteries and physical batteries, with chemical batteries being the most commonly used. They are composed of anode (positive electrode), cathode (negative electrode) and their electric contact fluid. As shown on the right. Its exterior is made of stainless steel and serves as the positive electrode. Its negative electrode is a stainless steel circular cover. There is a sealing ring insulated between the positive electrode and the negative electrode. The sealing ring is made of nylon. In addition to insulating, the sealing ring can also prevent electrolyte leakage. . There are many types of button batteries, most of which are named after the materials used, such as silver oxide batteries, button batteries, alkaline manganese batteries, etc.
