Composition research for capacitors with increased capacity. UACJ Foil develops technologies such as trace component and cube orientation control technologies that realize highly pure aluminum foil with excellent etching characteristics. This allows for manufacture of aluminum electrolytic capacitors with improved capacity and performance.
The aluminum foil which forms the anode of the capacitor will have its surface chemically highly etched to increase its surface area, and therefore its capacitance.
After that, the aluminium foil undergoes an anodic oxidation process which covers the etched foil structure with a dielectric which enables its use in the electrolytic capacitor.
Only during the late 1930s the hard-rolled aluminum foil was found to be able to provide capacitor anodes of improved capacitance. This property had not found any use until the 1960s when the aluminum electrolytic capacitor first appeared in the electronic industry.
Until the wound construction of aluminum foil capacitors, this type of capacitor was bulky and heavy. There are different sizes of capacitor ranging from 3 mm in diameter for 5 mm in height up to 90 mm for 210 mm .
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.
