| titleOfInvention | Porous aluminum foil for electrolytic capacitor prepared by laser photoetching and method |
| abstract | The invention relates to a porous aluminum foil for electrolytic capacitor preparation and a method thereof by laser irradiation, firstly, the cleaned aluminum foil is subjected to laser irradiation etching hole making to obtain the porous aluminum foil; the conditions for making the holes by laser irradiation etching are as follows: the power of a light source is 1W-50W, the pulse width of a laser is 5 femtoseconds-50 femtoseconds, the pulse repetition frequency is 10 KHz-50 MHz, and the moving speed is 100 mm/S-7000 mm/S; and cleaning and drying the porous aluminum foil to obtain the porous aluminum foil for the electrolytic capacitor. According to the invention, the porous aluminum foil for the aluminum electrolytic capacitor can be prepared by adjusting the power of a light source, the pulse width of laser and the pulse repetition frequency; the porous aluminum foil prepared by the method has the advantages of adjustable pore size, pore depth and pore distribution, can avoid environmental pollution, reduce the pollution of the aluminum foil and the like, and has the characteristics of short time, high efficiency, simple process, high processing precision and the like. |
