  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

  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 be

  At present, with the continuous development of China's super capacitors in many application fields, China's super capacitors will become a new strengths in the field of chemical power.   The super capacitor market for transportation accounts for the largest proportion, and is expected to reach 10 billion yuan in 2025. At the same time, the market scale in the fields of industrial and new energy super capacitors has also shown rapid growth.   In 2018, super capacitors were included in China's national special support projects and selected as key products in emerging industries. The Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology have issued a series of special policies to clearly support the field of super capacitors and new materials. This shows that the super capacitor industry has ushered in a good development opportunity, indicating the future growth prospects.   As a core basic
