Abstract
The invention provides a photopolymerization gel electrolyte-based aluminum electrolytic capacitor. The photopolymerization gel electrolyte-based aluminum electrolytic capacitor is characterized by comprising a housing and a core package, wherein the core package is sealed in the housing; a gel electrolyte is formed in the core package and between the core package and the housing; the gel electrolyte is a gel polymer compound which is obtained by polymerization of a solution system I and a solution system II under the trigger of UV light; the mixing proportion of the solution system I to the solution system II is (1:4) to (4:1); the solution system I can be an aqueous electrolyte and can also be a non-aqueous electrolyte; the solution system II comprises 85%-95% of a monomer, 2%-10% of a cross-linking agent and 0.1%-10% of a photoinitiator; and the monomer is a polymer compound which contains hydroxyl and carbon-carbon double bond functional groups and can be subjected to polymerization reaction or condensation polymerization. The aluminum electrolytic capacitor provided by the invention has good low-temperature performance, good room-temperature anti-surge voltage characteristics and good flame retardant property.
