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.

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).

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).

Can battery-connector joint technology be used in battery interconnecting?

Clamping of the joining partners may be a challenge if battery-connector joint designs get rather complicated, as in the case of multiple pouch cell tabs to busbar welds for instance. At this point, it may be concluded that the technology has the potential to be used in battery interconnecting but more research is necessary.

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 .
