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.
Step 1: Corrosion of aluminum foil. The manufacturing essentials of aluminum foil. In order to increase the area of war between the aluminum foil and the electrolyte, the appearance of the aluminum foil in the capacitor is not smooth. Instead, the appearance is formed into a rugged and unyielding shape by electrochemical corrosion.
The performance of aluminum electrolytic capacitors largely depends on the specific surface area of the anode foil. A high specific surface area is commonly obtained by electrochemical etching, so that high-density etched tunnels (>10 7 /cm 2) are formed on aluminum foil [, , ].
There are eleven steps in the manufacturing Aluminum electrolytic capacitor manufacturing process, and each step is critical. Step 1: Corrosion of aluminum foil. The manufacturing essentials of aluminum foil.
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.
With the continuous updating and iteration of electronic products, new anodic foil manufacturing technology is urgently needed to achieve the miniaturization and light weight of aluminum electrolytic capacitors by means of improving the effective specific surface area of the anodic foil.
