Super capacitors are between the range of capacitor and battery energy storage devices, China’s Heilongjiang, Harbin Jurong Corporation, through independent research and development of super-capacitors, which is technically a leading position in the international arena, with independent intellectual property rights, technical level of products with Russia, similar to similar products. Russia’s products are 17 th Annual International Electric Vehicle (EVS-17) evaluation is currently the most advanced super-capacitors, intellectual property worth 200 million U.S. dollars. It has a capacitor can quickly charge and discharge characteristics, but also has mechanism of electrochemical energy storage battery.
Super-capacitors can be divided into two categories: (1) carbon materials as electrodes, with electrode double-layer capacitance mechanism to store charge, commonly referred to as double-layer capacitors (DLC); (2) with ruthenium dioxide or a conductor polymers and other materials for the anode, oxidation-reduction reaction mechanism in order to store charge, commonly referred to as electrochemical capacitors.
As a new type of energy storage components, the capacitance of electrochemical capacitors can be level or even tens of thousands of high-dafala Farah, to achieve rapid charge and discharge and high current power generation and power than the battery has a higher density (up to 1,000 W / kg of magnitude ), and longer cycle life (charge and discharge times of up to 10 million), while at very low temperatures and other extreme environments, and no environmental pollution. These features make electrochemical capacitors in electric vehicles, communications, consumer and entertainment electronics, signal monitoring and other areas of power | voltage regulator applications have broad market prospects.
Some industry experts predict far as the Chinese market, the current annual demand of up to 2,150 million, while total demand for the entire Asia-Pacific region and more than 9,000 million. U.S. market research firm Frost & Sullivan recently released a report also forecasts that between 2002 and 2009, the global super-capacitor industry, production and sales of these two data, respectively 157% and 49% per year compound annual growth rate to maintain rapid growth.
