Is the button battery a lithium ion battery?

Button batteries are also divided into two categories: chemical batteries and physical batteries, and chemical batteries are the most common. They are composed of anode (positive electrode), cathode (negative electrode) and their electric contact. As shown on the right. Its appearance is made of stainless steel and used as a positive electrode. Its negative electrode is a stainless steel circular cover. There is a sealing ring between the positive electrode and the negative electrode for insulation. The sealing ring is made of nylon. The sealing ring is not only used for insulation, but also prevents 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, and alkaline manganese batteries. A button battery refers to a battery that looks like a button, which is actually a lithium-ion battery. Lithium is the lightest metal, so lithium-ion batteries have the advantages of lightness, durability, high stability, and long-lasting power. The disadvantage is that the power is small and the cost is high. So the use is mostly limited to precision instruments. Lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium-ion batteries have not been used for a long time. With the development of science and technology, lithium-ion batteries have now become the mainstream. Lithium ion batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance-price ratio are superior to those of lithium-ion batteries. Due to its own high-tech requirements, only a few companies in a few countries are producing such lithium metal batteries. With the increasing popularity of electronic watches, calculators, lighters, cameras and other household appliances, button batteries (also known as button batteries) have become more widely used. All kinds of counterfeit and inferior button batteries are also taking advantage of the fiction. Therefore, everyone must be cautious when buying button batteries and do not buy fake or shoddy products.
