Embodiment 1

[0200] Deposition of Rare Earth Doped Titanium Oxide High Dielectric Film by Immersion Method on Aluminum Foil Surface

[0201] Proportionally dissolve 3.5mmol / L titanium nitrate and 0.3mmol / L rare earth salt in deionized water, stir evenly, and prepare the treatment solution, marked as A.

[0202] At room temperature, immerse the corroded aluminum foil in the treatment solution A for 10min~10h. The soaking process can be supplemented by mechanical stirring.

[0203] Remove, rinse, and tumble dry.

[0204] Next, treat at a high temperature of 300~650°C for 10min~60min.

[0205] Then, anodic oxidation is performed to form a high-dielectric composite dielectric film on the surface of the aluminum foil.

Embodiment 2

[0207] Proportionally dissolve 3.5mmol / L titanium nitrate and 0.3mmol / L rare earth nitrate in deionized water, stir, and add 10mmol / L citric acid, and / or 2ml / L hydrogen peroxide H2O2, stir well, prepare the treatment solution, mark for B.

[0208] At room temperature, immerse the corroded aluminum foil in the treatment solution B for 3 to 30 minutes. The immersion process can be supplemented by mechanical stirring.

[0209] Remove, rinse, and tumble dry.

[0210] Next, treat at a high temperature of 300~650°C for 10min~60min.

[0211] Then, anodic oxidation is performed to form a high-dielectric composite dielectric film on the surface of the aluminum foil.

Embodiment 3

[0213] Electrodeposition of Rare Earth Doped Titanium Oxide High Dielectric Film on Aluminum Foil Surface

Abstract

The invention relates to manufacture of an integrated electrode with high specific volume which is an electrode material used in a capacitor, and relates to a process and method for depositing on a surface of a conductive substrate, especially on a metal surface such aluminum foil or nickel foam, to form cyanpolysiloxane, rear-earth oxides and multicomponent high-dielectric metal oxides so as to manufacture the integrated electrode with high specific volume and further process the integrated electrode with high specific volume into a capacitor.

Description

technical field [0001] The present invention relates to the manufacture of an electrode material used in a capacitor-a high specific volume integrated electrode, relates to the deposition and formation of cyanopolysiloxane on the surface of a conductive substrate, especially on the surface of metals such as aluminum foil and foamed nickel, and / or Or the process and method of rare earth metal oxides, multi-component high dielectric metal oxides, to make high specific volume integrated electrodes, and further process them into capacitors. Background technique [0002] High specific capacitance electrode technology is the key to realizing the miniaturization of capacitors. For example, electrode foil is the key material of aluminum electrolytic capacitors, and the specific capacitance of electrode foil directly determines the volume and energy density of aluminum electrolytic capacitors. [0003] The so-called high specific volume integrated electrode refers to a conductive su...
