Cylindrical lithium-ion battery cells are a type of rechargeable battery commonly used in a wide range of electronic devices, electric vehicles, and energy storage systems. They are characterized by their cylindrical shape, standardized sizes, and high energy density, making them versatile and suitable for various applications.
Cylindrical cells are named after their sizes (diameter in mm x height in mm). Current models of cylindrical batteries include 14650, 18650, 21700, 32650, 4680 (named by the standardised sizes of the battery, e.g. 14650 cylindrical cell is 14.5mm in diameter x 65.3mm in height).
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.
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).
Current models of cylindrical batteries include 14650, 18650, 21700, 32650, 4680 (named by the standardised sizes of the battery, e.g. 14650 cylindrical cell is 14.5mm in diameter x 65.3mm in height). 18650 represents the most mature technology, developed by SONY in 1992; 21700 is the most widely used cell format by Tesla EV.
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 global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%.
