Super electrolytic capacitor paper

Abstract

The invention relates to an electrolytic capacitor paper, in particular to a super electrolytic capacitor paper. The super electrolytic capacitor paper consists of the following components in percentage by weight: 10 to 80 percent of pineapple flax fiber and 20 to 90 percent of tencel papermaking. The super electrolytic capacitor paper has low paper tightness, high strength and small and uniform pore diameter; the capacitor paper is low in consumption due to the low paper tightness, and an internal resistance of a super capacitor is not increased; the capacitor paper is suitable for the processing of the super capacitor due to the high strength; and the super capacitor is small in leakage current due to the small pore diameter, so that the super capacitor paper is suitable for storing energy and is applied to the super capacitor.

Description

A kind of super electrolytic capacitor paper technical field The invention relates to an electrolytic capacitor paper, in particular to a super electrolytic capacitor paper. Background technique Electrolytic capacitors are one of the most important basic electronic components in electronic engineering. In addition to filtering, coupling and bypassing functions in electronic circuits, it also plays a special role in special circuits such as correction circuits, power circuits and AC motor starting circuits. Widely used in military industry, civilian communication equipment, audio-visual system, control electrical appliances and electronic instruments and other fields. Electrolytic capacitor paper is the gasket material for absorbing electrolyte in electrolytic capacitors, and its performance directly affects the quality of electrolytic capacitors. With the rapid development of electronic technology, electrolytic capacitors are rapidly developing towards miniaturization, ...
