High Frequency Ceramic Capacitors
It is suitable for high frequency circuit mica capacitors. In terms of structure, it can be divided into foil type and silver type. The silver-coated electrode is directly coated with a silver layer on the mica sheet by vacuum evaporation or sintering. Due to the elimination of the air gap, the temperature coefficient is greatly reduced, and the capacitance stability is also higher than that of the foil type. The frequency characteristics are good, the charge value is high, and the temperature coefficient is small, so it cannot be made into a large capacity. Widely used in high frequency electrical appliances and can be used as standard capacitors.
Faraday quasi-capacitor
Its theoretical model was first proposed by Conway, which is that electroactive substances undergo underpotential deposition on the electrode surface and near-surface or two-dimensional or quasi-two-dimensional space in the bulk phase, and highly reversible chemical adsorption, desorption and redox reactions occur. A capacitance related to the electrode charging potential is created. For Faraday quasi-capacitors, the process of storing charges includes not only the storage on the electric double layer, but also the redox reaction between electrolyte ions and electrode active materials. When the ions in the electrolyte (such as H+, OH-, K+ or Li+) diffuse from the solution to the electrode/solution interface under the action of an applied electric field, they will enter the active oxide on the surface of the electrode through the redox reaction on the interface. in the bulk phase, so that a large amount of charge is stored in the electrode.
Super capacitor
The area of the supercapacitor is based on a porous carbon material whose porous structure allows it to reach an area of 2000 m2/g, with some measures enabling a larger surface area. The distance the supercapacitor charges are separated is determined by the size of the electrolyte ions that are attracted to the charged electrodes. This distance (<10 Å) is smaller than what can be achieved with conventional capacitor film materials
