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).
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 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 .
