About this material
Aluminium carries the cathode because it passivates above 2 V: a thin oxide film forms and stops further reaction, which is exactly the behaviour copper cannot provide. Thickness is a compromise — 12 μm saves weight and cost, 20 μm resists the tension of a production coater.
Surface condition decides adhesion. A mill-finish foil with low wetting tension will shed a thick NMP-based coating during drying, so battery grades specify roughness and surface energy, and are supplied oil-free and edge-trimmed.
Documentation, controls and care
Quality controls
- Certificate of analysis per batch
- Moisture by Karl Fischer, reported per lot
- Trace metal screening
- Retained samples held for 12 months
Handling & storage
- Store in a dry environment below 30 °C, away from direct sunlight.
- Equilibrate to room temperature before opening to avoid condensation on the material.
- Dry at 60–80 °C under vacuum before use where the process requires it.
