Problems solved by technology

[0006] Aluminum electrolytic capacitors use electrolytic solution as the electrolyte, so there is a limitation of low conductivity and shortened life in the high-frequency region. In terms of reliability improvement, high-frequency characteristics, low loss, and low ESR (Equivalent Series Resistance: Equivalent series resistance), low impedance, and high heat generation due to ripple current, so there are limitations in safety such as smoke, combustion, and environmental tolerance

Description

technical field [0001] The present invention relates to a metal capacitor and a manufacturing method thereof, and more particularly, to a metal capacitor using a metal material as an electrolyte to significantly improve conductivity and a manufacturing method thereof. Background technique [0002] Conventionally, aluminum electrolytic capacitors are known as capacitors used for filtering power output from a power supply circuit to a constant value or for low-frequency bypass, and the manufacturing method thereof is as follows. [0003] First, in order to increase the surface area of ​​the aluminum foil and thereby increase the capacitance, a process of etching the surface of the aluminum foil is carried out. When the etching is complete, a forming process is performed to form the dielectric on the aluminum foil. When the cathode and anode aluminum foils are manufactured by performing etching and forming processes respectively, a slit process of cutting the aluminum foil and...
