Contaminants and oxide films are removed from the surface of this aluminium foil and the surface is roughened. With Ranafoil, wetability with coating mediums is improved, surface resistance is reduced and adhesiveness is improved by anchoring effects. This product is suitable for electrode materials in lithium batteries and electric double layer capacitors.
Ranafoil-A :
Foil surface is washed using alkali.
Ranafoil-B :
Foil surface is physically roughened using sandblasting.
Ranafoil-C :
Foil surface is roughened using chemical etching employing acid.
Ranafoil-A Example of use as electrodes in electric double layer capacitors
