    摘要: The present invention belongs to the technical field of electrode foils, and discloses an electrode structure and preparation methods thereof. The electrode structure comprises a substrate and a sintered body, wherein the sintered body is formed on the surface of the substrate, and the sintered body is provided with cracks that are formed after the hydration treatment of the sintered body. The continuity of cracks of the electrode structure was good, and the preparation method is suitable for industrial production. On the one hand, the electrode structure with cracks can effectively increase the bending strength and reduce the stress during the winding process of the electrode structure, thereby reducing the risk of fracture during the application process; on the other hand, it can improve the flexural strength of the electrode structure while maintaining the original high electrostatic capacity and lower leakage current value of the electrode structure, without negatively affecting the performance of the electrode structure.

    摘要: The present invention provides a method for producing a capacitor element having good LC characteristics, wherein, after a chemical conversion process to form a dielectric layer on the surface layer of an anode body obtained by forming a powder mainly comprising tungsten, followed by sintering, a semiconductor layer and a conductor layer are sequentially formed on the dielectric layer; an etching process is conducted before forming the dielectric layer to remove a natural oxide film formed on the surface layer on the outer surface and on the surface inside the pores of the anode body so as to adjust the film thickness to a range of 0.5 to 5.0 nm; and the chemical conversion process is conducted at a temperature from -4 to 18°C for 7 to 110 minutes after reaching a predetermined voltage.
