This is an aluminium foil that has had the contaminants and oxide film removed from its surface and the surface roughened. It is a material that improves the wettability with paints, lowers the surface electrical resistance and improves the adhesion through an anchor effect. It is suitable for electrode materials in electric double-layer capacitors and lithium batteries.

Ranafoil-A Example of use for electric double-layer capacitor electrodes.


Ranafoil-A: Foil that has a special surface cleaning treatment.
Ranafoil-E: Foil that has been physically roughened using chemical treatment.
Ranafoil-CB: Foil that has a coating on its surface.
