The sintered foil with 30 vol% starch has potential applications in aluminum electrolytic capacitors due to its high specific capacitance (0.886 μ F/cm 2) and anti-buckling performance (more than 120 times) that meet the requirements for winding. J. Both, The modern era of aluminum electrolytic capacitors.
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.
The specific capacitance of the sintered foils was predicted using the close-packed packing model, which can help establish a powder metallurgy method for preparing anode foil materials with high specific capacitance and anti-buckling performance for aluminum electrolytic capacitors.
Sintered foils are currently being considered as a promising material for anode foils in capacitors due to their high specific capacitance and anti-buckling performance, which meet the requirements for capacitor winding. In this article, sintered foils with added starch were produced using a protective atmosphere sintering process.
In contrast, an aluminum foil with a thickness of 120 μ m, produced using tunnel etching technology, has a lower expansion surface ratio of 65 or below. Therefore, the use of porous sintered foil significantly enhances the specific capacitance of the anode foil.
In addition, the specific capacitance of the anode foil prepared by non-equal diameter powder has a certain fluctuation. Among them, when the particle size is 3– 4 μm, the specific capacity under 375 V formation voltage is 0.887– 1.151 μF/cm 2, and the specific capacity under 520 V formation voltage is 0.617– 0.735 μF/cm 2.
