How many Li-ion cylindrical battery cells are there?
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.
How to design cylindrical Li-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).
What is a lithium ion cell?
Lithium-ion cells are the building blocks of battery packs, and they are available in various form factors and sizes. The three primary components of a lithium-ion cell are the cathode and anode, separated by an electrolyte. These parts are stacked together and placed in one of a few packages: cylindrical, pouch, or hard case prismatic.
How does a jelly roll work in a lithium ion battery?
The jelly roll is inserted into a cell housing and contacted on the anode and cathode sides. After electrolyte filling, the cell is sealed. Jelly rolls for cylindrical Li-ion battery cells differ in two basic designs: (1) With tabs (Design A and Design B) and tabless (Design C and Design D).
What are the different types of lithium ion cells?
Cylindricals: Cylindrical cells have their electrodes rolled up like a jelly roll and placed inside a cylindrical case. These cells are relatively small, and dimensionally stable during operation. 18650 Cells: 18650 cells are among the most widely used lithium-ion cell sizes. They measure 18mm in diameter and 65mm in length, hence the name.
Why are cylindrical battery cells so popular?
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).

Gases can build up in a cell over time or suddenly when the cell fails. At some point, and depending on the cell design, the gas pressure will cause the safety valve in the cell to release or the cell case to fail. A cell venting doesn''t necessarily mean it will go into thermal runaway, but a thermal runaway will be predated by the cell venting.
