The basic principle of supercapacitors is the same as other types of electric double-layer capacitors. They all use the electric double-layer structure composed of activated carbon porous electrodes and electrolyte to obtain a large capacity. The advantages of super capacitors have the following points: 1. A farad-level capacitance in a small volume; 2. No special charging [...]
The recovery of the European economic recovery is accompanied by multiple risks. Due to the impact of the new crown pneumonia epidemic, the European economy fell into recession in the first half of the year. Recently, the overall recovery of the European economy has shown momentum, but the economic performance is still mixed, accompanied by risks. [...]
The so-called mica capacitor is a capacitor that uses natural mica as the medium of the capacitor. Its production method is to use metal foil or spray a silver layer on the mica sheet as the electrode plate. Powder or sealing made in epoxy resin. The following are the Features of mica capacitors: ①The capacity range [...]
The two major economies of China and Europe should play the role of the world economy as a "twin engine" for stimulating world economic recovery. Since the outbreak of the new crown pneumonia, China and the EU have supported and helped each other. The vitality of Sino-European trade is a positive signal for both sides and [...]
Mica capacitor is a kind of capacitor, and its shape is mostly square. Mica capacitor uses natural mica as the medium between capacitor electrodes, so its withstand voltage and high performance are quite good. The electrode plate is made of metal foil or sprayed with a silver layer on the mica sheet. The electrode plate and [...]
