How long can the supercapacitor be fully charged? -Lithium - Ion Battery Equipment
What is the super capacitor? You can understand the supercapacitors as a small battery.
Super capacitors are very simple. As long as the pointed voltage is not enough. As for the discharge of the super capacitor, the voltage is decreased, and the current is determined according to the load. That current is also declining.
Super capacitors, also known as electrical chemical capacitors, dual -electric capacitors, golden capacitors, and Fara capacitors. It is an electrochemical element that developed from the 1970s and 1980s to store energy storage through polarized electrolytes in the 1970s and 1980s.
It is different from the traditional chemical power supply. It is a power supply between traditional capacitors and batteries and has special performance. It mainly relies on dual -electrodes and oxidation and reduction capacitor charge storage energy. However, the process of energy storage does not have a chemical reaction. This energy storage process is reversible, and it is precisely because this super capacitor can repeatedly charge and discharge hundreds of thousands of times.(Lithium - Ion Battery Equipment)
The specific details of the supercapacitors rely on the application and use of super capacitors. Due to manufacturers or specific application requirements, these materials may be slightly different. The commonality of all supercapacitors is that they include a positive electrode, a negative electrode, and the diaphragm between the two electrodes. The electrolyte fills the two pores separated from the two electrodes and the diaphragm.
The structure of the super capacitor is shown in the figure. It is composed of high -pairing porous electrode materials, collecting flows, porous battery diaphragms and electrolytes. The electrode material should be closely connected between the streaming to reduce the contact resistance; the diaphragm should meet the conditions of as much as possible and the lower electronic conductance as possible. Essence The type of electrolyte is selected according to the nature of the electrode material.
The components of supercapacitors can vary from products to products. This is determined by the geometric structure packaged by the super capacitor. For the placement of the prism or square packaging product parts, the internal structure is based on the setting of internal components, that is, the internal collector is squeezed out of the stack of each electrode. These collector pads will be welded to the terminal to extend the current path outside the capacitor.
For circular or cylindrical packaging products, the electrode is cut into scrolls. Finally, the electrode foil welded to the terminal to expand the external capacitor current path.
The basic principle, like other types of dual -layer capacitors, uses the dual -layer structure composed of activated carbon porous electrodes and electrolytes to obtain a large capacity.
The prominent advantage is that the power density is high, the charging time is short, the cycle life is long, and the working temperature range is wide. It is the largest capacity of the world's mass -produced dual -layer capacitors.
According to the differences in the energy storage mechanism, it can be divided into the following two categories:
Dual -electrocompating capacitance: It is generated by the charges through the direction of electrons or ions in the electrode/solution interface. For an electrode/solution system, a dual electrode layer is formed on the electrode -conductive electrode and ionic electrolyte interface. After applying an electric field on the two electrodes, the yin and cations in the solution migrate to positive and negative electrodes respectively, and form a dual electrode layer on the surface of the electrode. Attracts the dual -electrode layer stable, and a relatively stable potential difference between positive and negative poles. At this time, for a certain electrode, it will generate heterosexual ion charges such as the charge on the electrode within a certain distance (decentralized layer) to keep it in the electrical neutral. The charge is migrated and the current is generated in the external circuit, and the ion migration in the solution is migrated to the solution to be electrical neutral. This is the principle of charging and discharge of dual -electrocompatible capacitors.
