Integration of multiple applications of the portable consumer electronics products, the increasingly high demand for battery power, which is super-capacitors (also known as electric double layer capacitors (DLC) or electrochemical capacitors) has brought great business opportunities. As a new energy storage components, its capacity can be high level or even thousands of Da Fala Fala, and higher than the power density of batteries (up to 1,000 W / kg of magnitude), faster charging speed and longer cycle life (charge and discharge times up to 10 million), while at very low temperatures so extreme environments, and no environmental pollution.
because of these advantages, supercapacitors for portable electronics, solar energy products, electric toys, gas meter and electric vehicle has a wide application areas such as space. Some industry experts predict, just from the Chinese market, the current annual demand of up to 2,150 million, while total demand throughout the region and more than 9,000 million. U.S. market research Frost & Sullivan, recently released a report is also expected, between 2002 and 2009, the global super-capacitor industry both production and sales revenue data were 157% and 49% compound annual growth rate to maintain growth.
Chinese suppliers to actively enter the market
ultracapacitor industry in the super-capacitor, the United States, Japan and Russia, some companies with many years of research and development and technology accumulation, is currently leading these companies, such as United States Maxwell, Japan NEC, Panasonic, Tokin and Russia Econd companies, these companies now occupy most of the world market; In recent years, promising vast potential in this field prospect, some Chinese companies are actively involved in the industry, and has already begun to have some technical strength and industrial capacity.
the fifth held in Shenzhen China Hi-Tech Fair, Ltd. Jinzhou demonstrated capacity supercapacitor ultracapacitor products in its series, popular tour those concerns. Its products include spiral wound, laminated and other types of button, the capacity in the range between 0.33-270F range of applications covering solar lights, electric toys, portable products are widely use. It is reported that the company in 2002 starting in January is also involved in the national supercapacitors, Capacitor supplier. The home was established in 1998, the company assumed the state 863 plans electric vehicle project with super capacitors, Shanghai trolleybus to run off-line reconstruction and other projects; in the low-power applications, the super-capacitor as a backup power supply for the Class smart instrumentation, computers, toys, household appliances and electric fields; and its super-capacitor power can be used for a variety of vehicles, engine start, electric bicycles, electric motorcycles and electric buses, and other areas of the traction.
Up to Science and Technology, Shijiazhuang / Beijing Jin Zhengping ultracapacitor company mainly focused on short-term high-power applications. The company has formed a capacity range of 0.5-1000F, operating voltage 12-400V, maximum current of 400-2,000 A series of enlarged super-capacitors products in the temperature of -40 to 80 �� normal work environment. According to the company, its products from the basic parameters, the technology level is close to Russia, but the price is only 1 / 3, has a high price has now sold about 10,000.
Daqing Zhenfu large capacity capacitor technology is approved by the State Economic and Trade Commission, a national key industrial pilot projects, the company has an annual output of 1,000 million into the automatic production line capacitor able to provide 0.047F to 1000F series products can be used for CMOS dynamic and static memory standby power, communications, electronics products, such as standby power.
In addition, the country also has several other super-capacitor suppliers, such as Star Technology and Harbin, Beijing set a new energy company Giant capacity and so on, these companies are setting up the last two years, and in their respective areas of expertise for product development or product marketing. Meanwhile, the domestic Jiangxi, Jiangsu, Henan, Shaanxi and Tianjin and other cities have also introduced policies to support the provinces and enterprises to actively enter the super-capacitor energy storage components such emerging markets, such as the list of hundred of electronic components in China's Jiangxi Electronics companies are also seeking partners to jointly for the production of super-capacitors.
manufacturers to improve safety, reduce costs and develop applications with the new companies are emerging
, supercapacitors are also large-scale application in China is coming. domestic suppliers are also actively in size from a different perspective to deal with the problems facing applications. For example, because it is a relatively new industry, domestic suppliers are now active in the marketplace and technology promotion, more and more buyers start to understand and recognize supercapacitor . Moreover, as technology companies, Nanjing Jihua Wu Jun, deputy general manager pointed out, the current supplier is actively engaged in application development, helping buyers to develop a mature alternative.
and improve product safety for suppliers the attention. particularly in the high-power applications, a domestic company's executives pointed out that the super capacitor in the security issue, although the super-capacitor internal short circuit may occur, but he pointed out that as long as each is equipped with super-capacitor circuit management system , can be immediately identified and resolved the problem.
applications in high-power super capacitors to overcome the one-time problem of higher input costs, the domestic suppliers are also cost-effective by improving aspects of their positive efforts. The industry pointed out that the relative super-capacitors cost-effective to rely on batteries to reflect the superiority. to lead-acid batteries, for example, the current charge and discharge is generally 5,000 times, but the theoretical super-capacitor charge and discharge times of up to tens of thousands or even hundreds of thousands of times, in terms of the actual level of , domestic manufacturers in the Hai Aowei technology can achieve super-capacitor charge and discharge is 20,000. Thus, if the super-capacitor battery life is 4-5 times the price but only if its 3 times to may reflect a more cost-effective advantage to.
specific application development, domestic suppliers have started in their respective areas of expertise to achieve concrete application of the results. supercapacitors in terms of low power applications, many domestic manufacturers have developed a corresponding application or alternative access to the specific application of its products. to Jinzhou capacity supercapacitor's case, its products have been applied to solar highway lights, toy cars and computer backup power supply and other fields. Nanjing, China technology companies also set financial capacity of Beijing Science and Technology Development Co., Ltd. Business Cooperation, the latter of its products used in lighting control system into the city, it lost power in one section of the control center when an alarm automatically. According to the Deputy Science and Technology of China Nanjing set Wu Jun, manager of introduction, in the loss of power to maintain national standards for the timing is 20 seconds, and using the company's super-capacitors, will be extended to 120 seconds.
At present, domestic manufacturers are paying attention to high-power supercapacitor applications such as environment-friendly modes of transport, power DC control, vehicle emergency boot device, pulse power equipment. in the environment-friendly means of transport, science and technology involved in the Hai Aowei cable tram reconstruction project in Shanghai. mainly with the urban development, part of the intersection of the tram overhead line was abolished in these sections can make decisions with super capacitors power to further experimentation. The Harbin giant energy company's new super-capacity capacitor buses have also been conducted in the pilot environment.
Beijing as a set of satellite technology was established in April 2003 the new company, its SPSCAP supercapacitor also already used in vehicle start, power and geological surveying equipment.
