| description | The invention relates to a high specific volume ultra-thin negative electrode foil and a liquid aluminum electrolytic capacitor. The negative electrode foil comprises an aluminum base material and a dielectric layer, the surface of the aluminum base material is etched to form holes, and the dielectric layer is a coating rolled on the holes and the surface of the aluminum base material. Slurry of the coating is selected from the oxide dielectric particles of valve metal, organic resin, a dispersing agent and a solvent according to the mass ratio of 1: (0.1-1): (0.0001-0.01): (5-50), the surface of the aluminum base material with holes is coated with the slurry, the slurry is dried in a high-temperature furnace at the temperature of 100-300 DEG C, and then carbonization is carried out under the conditions that oxygen is isolated and the temperature is controlled to be 400-600 DEG C to form the coating before rolling. According to the negative electrode foil obtained through etching and rolling processes, the re |
