Pb2+ ino, added in ctching sohing, is electrodeposited on a alumiunm foil for electrolycic condenser to promote its capacitance. In addition, several factoral factors in etching process are varied to examine how they change the capacitance of the condenser. The capacitance of the condenser made of 0.1 ppm pb electrodeposited aluminum foil is enhanced about 20% than of conventional ane. It is thought out that the enhanement is the result of the act of PbO2, which existed for the conveting of electrodeposited Pb, as a promoter tunnel etching of aluminum foil.
