| titleOfInvention | Corrosion foil for aluminum electrolytic capacitor and preparation method thereof |
| abstract | The invention relates to a preparation method of a corrosion foil for an aluminum electrolytic capacitor and the corrosion foil prepared by the method. The preparation method comprises hole distribution corrosion and deep growth corrosion, wherein the hole distribution corrosion and the deep growth corrosion adopt alternating current of a combined waveform to carry out power-on corrosion on the aluminum foil, and the combined waveform is a triangular wave, a trapezoidal wave or a combined waveform of a square wave and a sine wave; the peak height of the triangular wave, the trapezoidal wave or the square wave is greater than the peak height of the sine wave. The corrosion foil prepared by the method provided by the invention has the advantages of no reduction of thickness, uniform corrosion layer, good mechanical strength and obvious increase of capacitance per unit area. The corrosion foil provided by the invention is applied to the aluminum electrolytic capacitor, and can fully meet the requirements of reducing the size of the capacitor and the cost of the capacitor. |
