Conclusion Anode foil for aluminum electrolytic capacitor was prepared by powder additive manufacturing technology. Based on the TG-DTG analysis, the sintering process was designed. Moreover, the effects of aluminum powder particle size and sintering temperature on electrical properties were investigated.
Anode foil for electrolytic capacitors were prepared using AM technology. The relationship between microstructure and electrical properties is studied. Sintering neck and particle size are the key factors affecting properties. The optimum preparation conditions are 630 °C and 5-6 μm.
To obtain higher capacitance, surface area of aluminum foil for electrolytic capacitor increases through the etching process. During the etching process, a DC or AC current is applied to the aluminum foil. This is done in a chloride solution to assist to dissolve the surface.
