Problems solved by technology

[0005] The Chinese invention patent (patent application number: 200310109194.0) discloses a low-density high-strength electrolytic capacitor paper. Since the fiber raw material used is the thinnest sisal with a width of 14-15 μm, the electrolytic capacitor paper made of it When used on supercapacitors, the biggest feature is that the leakage current is large, and the energy storage performance of the capacitor is not good.

example 2

[0018] Pineapple hemp pulp is beaten at 30°SR, paper is made by fourdrinier paper machine, the paper making process is as conventional, and the conventional indicators such as paper sheet detection quantity and strength are made into the leakage current, internal resistance, capacity and other indicators of supercapacitor test capacitors.

[0019] Reference example 3

[0020] The pineapple hemp pulp is beaten at 80°SR, and the paper is made by a rotary paper machine. The papermaking process is as conventional as the conventional process, and the conventional indicators such as the quantitative and strength of the paper are tested, and the leakage current, internal resistance, capacity and other indicators of the supercapacitor test capacitor are made.

example 4

[0022] Tencel pulp is beaten at 85°SR, and the cylinder paper machine is used for papermaking. The papermaking process is such as the conventional process, and the conventional indicators such as the quantitative and strength of the paper sheet are tested, and the leakage current, internal resistance, capacity and other indicators of the supercapacitor test capacitor are made.

example 5

[0024] Tencel fiber is beaten at 20°SR, and the paper is made by a side wave net paper machine. The papermaking process is like a conventional process, and the conventional indicators such as the quantitative and strength of the paper sheet are tested, and the leakage current, internal resistance, capacity and other indicators of the supercapacitor test capacitor are made.

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

technical field [0001] The invention relates to an electrolytic capacitor paper, in particular to a super electrolytic capacitor paper. Background technique [0002] 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. [0003] With the rapid development of electronic technology, electrolytic capacitors are rapidly developing towards miniaturization, high quality, high reli...
