Lithium button battery is shaped as a squat cylinder,typically 5 to 25 mm (0.197 to 0.984 in.) in diameter and 1 to 6 mm (0.039 to 0.236 in.) in height,similar to a button.Stainless steel typically forms the bottom body and positive terminal of the battery;insulated from it,the metal top cap forms the negative terminal.

What are the product features of lithium button battery?
The diaphragm in a lithium button battery is stamped into a small round piece with a diameter slightly larger than the positive and negative electrodes. Diaphragms can be selected according to the cell performance requirements.
Simply put, if there is no diaphragm in a lithium button battery, the positive and negative electrodes are in direct contact, i.e., short-circuited, which is why some button batteries inhibit the production of lithium dendritic crystals, in order to prevent them from piercing the diaphragm, causing a local short circuit, and resulting in a safety accident. Diaphragm is generally made of polyethylene and other polymer materials, non-conductive, its structure has many micro-pores, allowing lithium ions to pass through, although it is an insulator, but does not allow electrons to pass through the statement is not accurate.
Lithium button battery is small and easy to use, and is the main energy source applicable to industrial, medical, and microelectronic devices. Along with the development trend of Internet technology, there is an increasing demand for button batteries for notebook motherboards, wireless sensor networks, smoke alarms, portable medical devices, data collectors, electronic toys, smart remote controls, lock keys, computer peripherals, portable microphone devices, etc.
Although lithium button battery is small, there is a wide variety of model specifications, with different diameters and thicknesses, and different output voltages. Mainly silver oxide batteries, lithium manganese button cell, alkaline manganese batteries, etc.. According to the charging method can be divided into non-rechargeable and charging two methods, usually also called primary and secondary batteries, in addition to the volume and specifications, voltage is also a specific choice of the main parameters.
