Problems solved by technology

[0004] Conductive polymer solid chip aluminum electrolytic capacitors The main polymerization methods for low-voltage products are polythiophene or polypyrrole. These two methods can only produce conductive polymer solid chip aluminum electrolytic capacitors with a rated voltage of <16V, but higher voltage products cannot. Apply the above two methods to aggregate
Therefore, there is a lack of conductive polymer solid chip aluminum electrolytic capacitors with good electrical parameters and superior performance with a rated voltage greater than 16V

Description

technical field [0001] The invention relates to the technical field of capacitor manufacturing, in particular to a polymer electrode foil, a preparation method thereof, and a conductive polymer solid chip capacitor. Background technique [0002] Conductive polymer solid chip aluminum electrolytic capacitors are chip solid aluminum electrolytic capacitors that use high-conductivity polymer materials as cathodes. They have superior performance beyond existing liquid chip aluminum electrolytic capacitors and solid chip tantalum electrolytic capacitors. Conductive polymer solid chip aluminum electrolytic capacitors do not need to be used within the rated voltage range, have extremely low equivalent series resistance (ESR for short), have a strong ability to reduce ripple voltage, and allow greater ripple current to pass. Conductive polymer solid chip aluminum electrolytic capacitors have an impedance curve that approximates the characteristics of an ideal capacitor at high frequ...
