Supercapacitor industry market prospects (a)
Supercapacitor energy storage device as a new, significant features and advantages, can replace traditional batteries in some areas, in the energy saving is increasingly becoming the subject today, its application has drawn increasing attention around the world.
Supercapacitors are national attention to the industrialization
United States, Japan, Russia, Switzerland, South Korea, France, some companies with many years of research and development and technology accumulation, is currently leading the
Domestic R & D in high-capacity supercapacitor more than 50 manufacturers, to mass production and to achieve a practical level more than 10 manufacturers only
The industrialization of the super capacitor, the United States, Japan, Russia, Switzerland, South Korea, France, some companies with many years of research and development and technology accumulation, the current leader. Such as the United States, Maxwel, Japan, Nec, Panasonic, Tokin and Russia Econd companies, these companies now occupy most of the global market. The main production enterprises abroad: the United States Maxwell company, Russia's Econd company, Elit, Japan's Elna Company, Panasonic Corporation, Nec-Tokin Corporation, South Korea's Ness companies, Korchip company, Nuintek companies.
United States, Japan, Korea and other countries have been developing high power and high specific energy than the super-capacitors. In the study of super-capacitors, are developing a lot of work in a variety of electrolytes have a higher energy than the electrode material. The material currently used in supercapacitors are carbon-based materials, metal oxides and hydrates the three materials and conductive polymer materials.
An early start in foreign research supercapacitor technology is relatively mature. They are the super-capacitors as a national key research projects and development projects, recent and proposed long-term development plans. Esma Russia is the production of inorganic hybrid supercapacitor representatives, however, Esma currently there is no scale production capacity. Moreover, Russia's Elit company, Saft France, the United States in the Cooper company, Japan's Nec and Panasonic have also invested huge capital for high-capacity supercapacitor of large-scale production.
In 2007, the global scale of the industry coin super capacitor is 10.2 billion U.S. dollars, convoluted and large industrial scale supercapacitor 34.8 billion U.S. dollars, the total size of super-capacitor industry 4.5 billion U.S. dollars, up 45%; projected 2008 global button-type industrial scale supercapacitor 15.3 billion, convoluted and large industrial scale supercapacitor 52.2 billion U.S. dollars, the total size of super-capacitor industry was 67.5 billion U.S. dollars, an increase of 50%.
In recent years, as optimistic about the prospects for broad application in this area, some Chinese companies have begun to actively get involved in this industry, and already have a certain amount of technical strength and industrial capacity.
Domestic R & D in high-capacity supercapacitor more than 50 manufacturers, however, to mass production and reach a practical level more than 10 manufacturers only. Haiao Wei Technology Development Co., Ltd. on the development of the "car with super capacitors" in the technology is more advanced. Compared with foreign manufacturers products, products with similar foreign products Aowei electrical and physical properties are close to some of the performance has more than similar foreign products. Overall, the company's products have reached international advanced level of similar products.
Currently, most domestic manufacturers produce liquid double layer capacitors, it is important enterprises in Jinzhou Fu Chen, the Beijing Star set, a dozen companies on the Hai Aowei. Jinzhou Fu Chen is the largest professional manufacturer of super-capacitors, the main production type and winding button supercapacitor. Beijing set to produce Star convoluted and large capacitors.
Huge potential market demand
As the capacitor has a super fast charge and discharge, environmental pollution, long cycle life, etc., have to become a new type of green energy in this century
The current demand of the Chinese market up to 21.5 million years, about 120 million watts, and every year the growth rate of about 50%
21st century, with global warming, lack of resources, countries and regions all over the world are developing new green energy sources, while the super-capacitor materials used in production is generally green. Therefore, the super-capacitor as a key development in this century one of the new storage products, is more and more countries and companies competing to develop and produce. 10 years ago, the super capacitor can only sell a few each year the number, and the price is very expensive, about $ 1 -2 USD / Farah, now, the super capacitor has been used as a standard product in large quantities supplied to the market, prices are significantly lower, on average 0.01 USD -0.02 USD / Farah.
Three-phase energy meter multi-function high-end data storage is greater than the ordinary power meter, and the traditional lithium batteries power the situation did not occur, resulting in a super-capacitor on the power meter applications.
Allegedly, the Chinese-made super capacitor has occupied 60% -70% of market share.
In addition, the country also has several other super-capacitor suppliers, such as the huge volume of new energy companies in Harbin 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 China, Jiangxi Province, one hundred electronic components electronic letter of the company is also seeking partners to jointly carry out the production of super-capacitors.
In 2005, the total size of China's super-capacitor industry reached 3.9 billion in 2004, 57.2% of 2.48 billion yuan, of which, button supercapacitors 4000 million, convoluted and large super-capacitors is 3.5 million; 2006 Industry total size of 5.7 billion yuan, up 46.2% growth rate, which, button supercapacitor market of 9000 million, convoluted and large super-capacitors of 4.8 billion; the total size of industry in 2007 reached 860 million yuan, increasing Speed up to 50%, of which, button supercapacitor market of 1.4 billion, convoluted and large super-capacitors is 7.2 billion; the total size of 2008 is expected to reach 1.33 billion industry, the growth rate up to 55%, of which , Button-type supercapacitor market reach 210 million yuan, winding type and size of a large super-capacitors of up to 1.12 billion market.
As new companies continue to emerge, supercapacitors are also large-scale application in China is coming. Domestic suppliers are active in different ways to deal with the problems faced by large-scale application.
Improve product safety for suppliers attention. Especially in the high-power applications, a domestic company's top super-capacitors that in security issues, although the super-capacitor internal short circuit can occur, but he pointed out that as long as each is equipped with super-capacitor circuit management system, can be timely identify problems and solve the problem.
Super-capacitors in power applications to overcome the one-time issue of high input costs, domestic suppliers are also active efforts to improve their cost performance. To lead-acid batteries, for example, generally charge and discharge current 5000, but the super capacitor charge and discharge times in theory up to tens of thousands or even hundreds of thousands of times, the actual level, the domestic manufacturers in the technology of super Hai Aowei capacitor can charge and discharge have been 20,000 times. Thus, if the super-capacitor battery service life is 4-5 times the price of its 3 times only, then it can be demonstrated to be more cost-effective competitive advantage.
