Design, Properties, and Manufacturing of Cylindrical Li
In the last 3 years, cylindrical cells have gained strong relevance and popularity among automotive manufacturers, mainly driven by innovative cell designs, such as the Tesla
Cylindrical lithium battery cells are generally used in power batteries, such as the typical 21700 battery cells carried in the Tesla Model 3, which once made 21700 popular in the battery cell market. However, cylindrical cells are not the only advantages; their shortcomings are also obvious.
This paper investigates 19 Li-ion cylindrical battery cells from four cell manufacturers in four formats (18650, 20700, 21700, and 4680). We aim to systematically capture the design features, such as tab design and quality parameters, such as manufacturing tolerances and generically describe cylindrical cells.
There are many types of cylindrical cells, such as 14650, 17490, 18650, 21700, 26650 and so on. Cylindrical lithium batteries are more prevalent in Japanese and Korean lithium battery companies, and there are also companies of appropriate scale in China that produce cylindrical lithium batteries. Ⅲ.
For instance, “65” represents a height of 65mm. Fifth Digit: The fifth digit indicates the cylindrical shape of the cell. Typically, it's “0” for cylindrical cells. By following this naming convention, we can easily identify the size and shape of cylindrical lithium-ion battery cells.
A generic overview of designing cylindrical Li-ion battery cells. Function 1: Two types of jelly roll designs can be distinguished: With tabs and tabless. Jelly rolls with tabs can be realized with a single tab (Design A) or several tabs in a multi-tab design (Design B).
The following is a common cylindrical cell structure; see the image below for details: Ordinary cylindrical lithium-ion batteries consist of a casing, a cap, a positive electrode, a negative electrode, a separator, and an electrolyte. Generally, the battery casing is the battery's negative electrode, and the cap is the battery's positive electrode.
