Tabless design
A cylindrical-cell construction in which the whole uncoated edge of each foil is folded and welded to the end cap instead of one or two narrow tabs. The current path shortens from metres to millimetres, cutting resistance and heating in large-format cells.
- Also called
- full-tab, shingled tab
Example
Lithium-ion chemistries and cell formats: an example situation
Two cylindrical cells can share dimensions yet differ in cathode, capacity and current limits.
Read Tabless design alongside Cylindrical cell in this context. A cell made by winding the electrodes into a jelly roll and sealing it in a round metal can. Sizes are named by their dimensions: a 21700 cell is 21 mm across and 70 mm long.
Use in Lemonergy
Separate chemistry from form factor.
This is a reference concept. No executable Lemonergy block has been verified for this term.
