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.
Moreover, using high-nickel cathode materials exacerbates this sensitivity to curvature, making it a crucial design consideration. Unlike flat-sheet batteries, cylindrical batteries require a tailored design approach that optimizes the N/P ratio while accounting for electrode curvature.
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 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.
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.
The naming rules for cylindrical lithium-ion battery cells follows a standardized format based on the cell’s dimensions, and usually represented by a five-digit code, where each digit provides specific information about the cell’s dimensions. Here’s a breakdown of the representation: What does 18650 means?
