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.
Module structure and optimization descriptions The module structure surrounding battery cells should be optimized to maximize cell volume or weight while satisfying mechanical and thermal safety constraints. This section presents the basic module structure used in this study and summarizes the optimization process.
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:
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).
