Problems solved by technology

Similarly, when this conductive polymer solid electrolyte is applied to a conductive polymer solid chip aluminum electrolytic capacitor, there are large differences in the capacity, loss and ESR of the solid capacitor, and it is not yet possible to obtain a solid capacitor with specific performance.
Moreover, the current conductive polymer solid chip aluminum electrolytic capacitors are mainly used in 2V-6.3V products, and cannot be used in other high-capacity products

Abstract

The present invention relates to a chemical polymerization solution, a conductive polymer solid slice aluminum electrolytic capacitor and a preparation method thereof, and relates to the technical field of production of conductive polymer solid slice aluminum electrolytic capacitors. The chemical polymerization solution comprises the compositions of percentage by weight: 0.1-20% of a monomer, 2-20% of oxygenant, 60-93% of solvent, and 0.5-10% of coupling agent. The chemical polymerization solution is configured to prepare a solid electrolyte layer with controllable performances to obtain a capacitor with expected performances. The preparation method of the conductive polymer solid slice aluminum electrolytic capacitor employs premixed solution, a chemical polymerization solution and mixedliquor to perform multi-time chemical polymerization processing until the compact and uniform solid electrolyte layer is formed at the surface of an aluminum foil to prepare the capacitor, and therefore the method is simple. The conductive polymer solid slice aluminum electrolytic capacitor prepared by the chemical polymerization solution is good in electric parameter and excellent in performance,and can be applied to the high-capacity products.
