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: PA0 the obtaining of a connections strip made of aluminium, having anode contacts, PA0 the fixing, to the anode contacts, of aluminium blocks either by sintering or by the spraying of molten aluminium, PA0 the anodization of the aluminium blocks; PA0 the impregnation of the blocks with the electrolyte; PA0 the positioning of the cathode contacts.
