The cylindrical cells have high energy density, high power, as well as high performance and long calendar life. The purpose of this document is to introduce a structure of a cylindrical lithium-ion cell. Figure 3 demonstrates a structure of a cylindrical lithium-ion battery cell.
Cylindrical Lithium-ion Batteries have been used in many electronic devices. The electrochemical cell of the batteries consists of a layer of positive electrode, a layer of negative electrode and two layers of separator. To assemble the electrochemical cell into a case of the battery, these layers are rolled up to make a jellyroll.
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).
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 tabless design. This paper investigates 19 Li-ion cylindrical battery cells from four cell manufacturers in four formats (18650, 20700, 21700, and 4680).
