Electrode wrinkling and buckling
Out-of-plane waves or folds in an electrode. In production they come from calendering, where the coated area stretches more than the bare foil edge, and from uneven web tension in winding; in service, electrode expansion can buckle a tightly wound jelly roll. Wrinkles leave uneven gaps and pressure that cause local lithium plating or separator damage.
- Also called
- wrinkling, buckling, foil wrinkles, jelly-roll deformation
Example
Manufacturing: an example situation
An electrode can meet coating mass targets but fail adhesion or moisture checks later.
Read Electrode wrinkling and buckling alongside Calendering in this context. Compressing a dried electrode coating between rollers to set its thickness, density and porosity. It is one of the electrode-making steps in cell production.
Use in Lemonergy
Place operations and quality checks in process order.
