The cylindrical battery shell has high voltage resistance and will not cause swelling of square or soft-packaged batteries during use. The cylindrical lithium battery cell size is larger. When the current is discharged, the internal temperature of the winding core is relatively high.
Cylindrical lithium batteries are more suitable for large-volume automated combination production. Large-volume lithium-ion batteries such as electric bicycles and electric motorcycles are basically produced from cylindrical lithium batteries. Not only that, cylindrical lithium batteries are also recognized as green and healthy batteries.
Cylindrical lithium ion battery pack is also often used as power batteries for electric vehicles, such as two wheeler electric bike, tricycles, etc., to provide electricity for cars and replace fuel vehicles, which is very environmentally friendly How to classify different types of cylindrical lithium-ion batteries?
The structure of cylindrical lithium-ion cell The round lithium battery refers to the cylindrical lithium-ion cell. The earliest cylindrical lithium-ion cell was the 18650 lithium battery invented by the Japanese company SONY in 1992. Due to the long history of the 18650 cylindrical lithium-ion cell, the popularity of the market is very high.
Cylindrical batteries can be divided into lithium iron phosphate batteries, lithium cobalt oxide batteries, lithium manganate batteries, and cobalt-manganese hybrid batteries based on filler materials. According to the type of shell, cylindrical lithium batteries can be steel shell lithium batteries and polymer shell lithium batteries. Part 1.
The major differences between both batteries are as under: ● The shape of cylindrical lithium batteries are cylindrical and are made with metal casing, and lithium prismatic cell have a rectangular or square shape. ● Cylindrical batteries have an electrode core surrounded by an electrolyte and separator.
