Is the Button Battery a Lithium Battery or a Dry Battery?

Many people have doubts about whether button batteries are lithium batteries or dry batteries?

In fact, to put it simply, rechargeable button batteries are lithium batteries. Non-rechargeable button cells are dry batteries.

Those starting with CR, such as CR2025 and CR2016, are disposable batteries with a nominal voltage of 3.0V.

Those starting with AG, such as AG1 to AG10, are disposable batteries with a nominal voltage of 1.5V.

lithium battery: A common disposable lithium battery is a lithium manganese battery (code C) with a nominal voltage of 3 V. Another less common type of disposable lithium battery is the lithium-fluorocarbon battery (code B), with a nominal voltage of 3 V. In addition, there is a commonly used secondary lithium battery called ML lithium battery (codenamed ML), with a nominal voltage of 3V. Lithium battery size numbers usually use the new numbering method of IEC. The first two digits are the diameter (unit: mm), and the last two digits are the thickness (unit: 0.1mm). Take the closest number between the two. For example, the approximate dimensions of CR2032 are 20mm in diameter and 3.2mm in thickness. Application: Due to their small size, button batteries have been widely used in various micro electronic products, with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm. Generally used as a backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, 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 consist of an anode (positive electrode), a cathode (negative electrode), and an electrolyte. 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, lithium batteries, alkaline manganese batteries, etc.
