The Supercapacitors: its Basic Principles, Classification, and its Electrical Performance

Image
  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 high capacity 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 Scale of Chinese Super Capacitor Market will Reach 13.84 Billion yuan in 2020

 Gao Bo, Secretary General of the Super Capacitor Industry Alliance, said on January 6: "the super capacitors have the advantages of fast charging, high power, long cycle life, strong temperature adaptability, environmental protection and no pollution. With the further development of the super capacitor application market, we firmly believe that super capacitors will become an important member of the energy storage family."   The super capacitor C hina  is a new type of energy storage device between traditional capacitors and batteries. Its mechanism is physical energy storage. The device does not generate heat. It has the advantages of large power, long life and favorable security. It is irreplaceable in many applications. Its application fields mainly include: the backup power supply for low-power electronic equipment, replacement power supply or main power supply; the power supply electric for the vehicle and hybrid vehicle; renewable energy power generation and energy...

The Improvement and Market Promotion of Supercapacitors Are Proceeding Rapidly

Image
 Supercapacitors are going beyond batteries, providing advantages of safety, fast charging and size, and at the same time, providing help to eliminate complex battery management systems in automotive, grid, and IT applications.   Perhaps in the near future, supercapacitors will eventually "replace" the current lithium-ion battery technology. In the next 20 years, more and more supercapacitors will be used in various industries. China is the market with the most potential for development of supercapacitors. In the future, the improved supercapacitors and their variants are microgrids, trains, trams, trucks, heavy off-road vehicles, taking advantages of energy collection to provide tiny uninterrupted power supply for IoT nodes, and provide huge opportunities for giant power supply of 1 MW/hour for hospitals and data centers.   The potential advantages of fast charging supercapacitor  technology are as follows: "You can charge them quickly because the only step is to pu...

The Difference between Supercapacitor and Battery

Image
Ultracapacitor VS Battery The supercapacitor is a kind of electrode material made of carbon-based active material, conductive carbon black, and binder. The polarized electrolyte is used to adsorb the positive and negative ions in the electrolyte to form an electric double layer structure for energy storage. The energy storage process basically does not  occur chemical reactions, so the cycle life is very long. The difference between supercapacitor and battery   are as follows:   For batteries, for example, lead-acid batteries use lead plates filled with spongy lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 1.28% dilute sulfuric acid as the electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy. When the battery is discharged, the metallic lead is the negative electrode and undergoes an oxidation reaction and is oxidi...
