Tunnel etching technology is economic and effective method for making high capacitance anode foil for medium/high voltage electrolytic capacitor. The method usually is three step which consist of pretreatment, firth etching and second etching. The higher capacitance maybe attained by add additive in pretreatment. Chloride acid is most importance composition in first etching step. Pit density is improved and pit limit length is shorted by add sulfuric acid. Diameter of pit tunnel can be enlarged by second etching.
