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).
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.
What is a cylinder Li-ion battery?
Cylindrical Li-ion battery cells consist of (i) a jelly roll, a wound composite consisting of a cathode, an anode, and two separators, and (ii) a cell housing consisting of a can and a cap . Current and heat transport between the jelly roll and the cell housing is traditionally conducted by contacting elements called tabs .
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).
