Embodiment 1

[0021] The nickel foil is used as the collector electrode 1, the carbonaceous active material is used as the positive and negative electrodes, that is, the carbonaceous polar electrode 2, and the 100Ω membrane resistor 4 is embedded in the center of the porous diaphragm 3, and assembled into a super power grid with a rated voltage of 220V and a Faraday capacity of 3.5F. capacitor.

Embodiment 2

[0023] The collector electrode 1, the carbonaceous polar electrode 2, the porous diaphragm 3, the membrane resistor 4, etc. were prepared in the same manner as in Example 1. The difference is that the membrane resistor 4 used is 200Ω, assembled to a rated voltage of 400V, and a Faraday capacity of 1.5F.

Embodiment 3

[0025] The collector electrode 1, the carbonaceous polar electrode 2, the porous diaphragm 3, the membrane resistor 4, etc. were prepared in the same manner as in Example 1. The difference is that the membrane resistor 4 used is 400Ω, assembled to a rated voltage of 500V, and a Faraday capacity of 1.0F.

Abstract

This invention relates to super capacitor. The capacitor is inner stack up series mode, interlayer film resistance is brought to conquer inner uniform voltage problem in multi monomer inner series high voltage super capacitor. The structure of the super capacitor is simple, and it is easy to make high voltage, large capacity and high performance capacitor.

Description

technical field [0001] The invention relates to a supercapacitor and belongs to the field of electrochemical double-layer supercapacitors. technical background [0002] At present, supercapacitors made by lamination technology mainly use carbon-carbon polar electrodes and carbon and metal oxide polar electrodes such as nickel oxide, etc. No matter what kind of polar electrodes are used, they are generally processed from powder materials. The electrolyte is mostly potassium hydroxide aqueous solution. This technology is relatively mature at home and abroad, the price is low, and it has been used in industrial products. The problem is that the working voltage of this electrolyte is relatively low and generally works at one volt, because the theoretical limit of the electrochemical decomposition voltage of this electrolyte is 1.4 volts. If this voltage is exceeded, the entire capacitor working system will be destroyed. In order to obtain a higher operating voltage, it is neces...
