Abstract
A method for the fabrication of aluminium electrolytic capacitors with solid or gelled liquid electrolyte, as well as the capacitor obtained by this method are disclosed. The method comprising the following steps: the obtaining of a connections strip made of aluminium, having anode contacts, the fixing, to the anode contacts, of aluminium blocks either by sintering or by the spraying of molten aluminium, the anodization of the aluminium blocks; the impregnation of the blocks with the electrolyte; the positioning of the cathode contacts.
Claims17
A method for the fabrication of an aluminum electrolytic capacitor with a solid or gelled liquid electrolyte, comprising the steps of:
- obtaining an aluminum connection strip, said strip having anode contacts,
- fixing to the anode contacts, aluminum blocks by sintering or by the spraying of molten aluminum,
- anodizing said aluminum blocks;
- impregnating said blocks with said electrolyte;
- and
- electrically connecting cathode contacts to said electrolyte.
An aluminum electrolyte capacitor with a solid or gelled electrolyte, comprising:
- an aluminum anode contact,
- aluminum blocks attached to opposing sides of said anode, the surface of said blocks being anodized,
- a coating of electrolyte on said blocks, and
- a cathode contact electrically connected to said electrolyte.
