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 the difference between a cylindrical and a prismatic Lithium battery?
Due to the round shape, the packing density of electrically connected cylindrical LIB is lower than the packing density of prismatic LIB. In terms of safety, the housing stability of the cylindrical and the hard-case cell is considerably higher than the pouch cell housing, which requires additional housing stability as part of a battery system.
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 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 .
What are the different shapes of lithium-ion batteries?
Pascalstrasse 8-9, 10587 Berlin, Germany Abstract Different shapes of lithium-ion batteries (LIB) are competing as energy storages for the automobile application. The shapes can be divided into cylindrical and prismatic, whereas the prismatic shape can be further divided in regard to the housing stability in Hard-Case and Pouch.
