Cylindrical battery

Cylindrical battery is a kind of battery with high capacity, long cycle life and wide ambient temperature.It is divided into lithium iron phosphate, lithium cobalt acid, lithium manganese acid, cobalt manganese mixture, ternary materials and other different systems, the shell is divided into steel shell and polymer, different materials system battery has different advantages.Mainly in the steel shell cylindrical lithium cobalt acid, lithium iron phosphate battery - based.Common specifications and models are: 18650, 26650, 21700 and so on. It is widely used in power tools, solar lamps, lawn lamps, backup energy, toy models.etc.

 

Take 18650 as an example:

The 18650 is the ancestor of the lithium-ion battery, a standard lithium-ion battery model adopted by the Japanese company SONY in order to save costs. 18 represents the diameter of 18mm, 65 represents the length of 65mm, and 0 represents the cylindrical battery.
