  Conventional capacitors can only meet the requirements of circuit operation with a simple structure and small load, but it is difficult to store charge for circuit operation with a large load. In recent years, the popularization and application of supercaps have effectively solved the problem of large load circuit operation and ensured the normal performance of power electronic equipment.   Super capacitor advantages   Ultra capacitors are the upgrade of ordinary capacitor devices, and many improvements have been made to the early capacitors. The main advantages are (1) capacitance. The conventional capacitors used in the early stage have small capacitor storage capacity, which can only meet the needs of small load circuit; while the capacitor level of super capacitor can reach farad level, which can meet the needs of more complex circuit operation. (2) Circuit. Ultra capacitor has a low requirement on the circuit structure. It does not need to set up a special charging circuit and c

  Super capacitor has a very wide range of uses. Combined with high energy density materials such as fuel cells, Supercap provides fast energy release to meet high power requirements, so that fuel cells can be used only as energy sources. At present, the energy density of Super capacitor/ultra capacitor can reach as high as 20 kW/kg and has begun to occupy the market between traditional capacitors and batteries.     In applications requiring high reliability but not high energy requirement, Supercapacitor can be used to replace traditional batteries, or UltraCap can be combined with batteries, which can be used in situations requiring high energy, and smaller and more economical batteries can be used.   The ESR value of ultra capacitor is very low, so it can output more current and absorb large current quickly. Compared with chemical charging principle, Supercapacitor's working principle makes the product performance more stable, so the service life of ultracapacitor will be longer

  Super capacitor can maintain long service life without failure as long as it works within the specified operating parameters. Super capacitor will last longer than most other electronic components in any given application, which is why ultra capacitor is the best transmission device in harsh environments.   However, if used improperly, Super capacitor  will also be damaged in advance, although there are not many reasons for the premature damage of ultra capacitor (the following items). Please note the following to ensure that the ultra capacitor in the system achieves the longest service life.   Working temperature: Super capacitor does not generate or provide power or energy through electrochemical reactions. Simply , it is achieved by static electricity. Obviously, electrochemical reactions in super capacitor are not only non-existent but also unnecessary. Higher temperature will catalyze the chemical reaction and accelerate the reaction rate. This applies equally to super caps bec

  In these days, the energy storage systems are playing an increasingly important role in different fields, and the relatively typical fields are like electric vehicles, power systems and some other fields. In this context, the super capacitors , as an energy storage technology, possesses excellent performances such as high power density, maintenance-free, and long life, and it have become the focus of attention in academia and industry.   The basic principles and the classification of the supercapacitors This section mainly will introduce the electrochemical mechanism of supercapacitors. The energy storage in supercapacitors is mainly in the interface between electrodes and electrolytes. This energy storage method has a great relationship with the electrode materials used. When the two electrodes of a supercapacitor are made from different types of materials, in this case, a comprehensive analysis of the energy storage mechanism of the product will not fully understand the working pri

  Supercapacitor, also known as electrochemical capacitor, double layer capacitor, gold capacitor, Farad capacitor, is an electrochemical component developed from the 1970s and 1980s to store energy through polarized electrolyte. Above is the supercapacitor definition. It is different from the traditional chemical power supply. It is a kind of power supply with special performance between the traditional capacitor and battery, mainly relying on double layer and redox pseudocapacitor charge storage of electrical energy. However, there is no chemical reaction during the energy storage process, which is reversible and types of supercapacitors can be recharged and discharged hundreds of thousands of times.   Supercapacitors are characterized by:   (1) Supercapacitors have fast charging speed, charging 10 seconds to 10 minutes can reach more than 95% of its rated capacity.   (2) Long cycle life, deep charging and discharging cycle times up to 1 ~ 500,000 times, no "memory effect".

  In applications where high reliability is required and energy requirements are not high, supercapacitors can be used instead of conventional batteries, or supercapacitors and batteries can be combined. Smaller and more economical batteries can be used in applications with high energy requirements.   Notice for using supercapacitors properly:   1. Supercapacitors have a fixed polarity. The polarity should be confirmed before use.   2. Supercapacitors should be used at the following nominal voltages. When the capacitor voltage exceeds the nominal voltage, it will cause the electrolyte to decompose, and the capacitor will heat up, reducing capacity, increasing internal resistance, shortening life, and in some cases, causing the capacitor to collapse.   3. Supercapacitors should not be used in high frequency charging and discharging circuits, high frequency rapid charging and discharging will lead to internal heating, capacity degradation, increased internal resistance, and in some cases

  Supercapacitor, also known as Electrical Doule-Layer Capacitor (EDLC), Gold Capacitor, Farad capacitor. The biggest difference between capacitor and supercapacitor is that supercapacitor is an electrochemical physical component, but does not react chemically itself, the supercapacitor has a particularly large storage capacity, reaching farad-level capacity. How do you increase the area of the two poles? Supercapacitors store energy by injecting electrolytes. Under the action of the electrode, the charge on the electrode surface will attract the heterogeneous ions in the surrounding electrolyte solution, causing these ions to attach to the electrode surface to form a double charge layer, constituting a double layer capacitance.   Because the distance between the two charge layers is very small (generally less than 0.5mm), and use of special electrode structure is adopted, the surface area of the electrodes is increased by ten thousandfold, resulting in a tremendous amount of electrica
