2013-2016 China Supercapacitor Market Size Forecast
In terms of market supply, out of promising prospects for future applications, there have been more and more manufacturers participating in this market competition in recent years. Among them, Shanghai Aowei Technology Development Co., Ltd., Shenzhen Modern Time New Energy Technology Co., Ltd., and Beijing Xingxing A group of domestic domestic manufacturers, such as United Electronic Technology Co., Ltd., Jinzhou Kaimei Energy Co., Ltd., and Harbin Jurong New Energy Co., Ltd., have gradually risen. The international brands include the United States MAXWELL, South Korea LSMtron, Nesscap, Japan's Panasonic, NEC-TOKIN. And so on. As a typical capital-intensive industry, supercapacitors are in a stage of rapid development, in addition to continuing to make breakthroughs in key technologies (such as electrodes, electrolytes, and diaphragm materials), expanding production scale to achieve better economies of scale. , Reduce the use of cost, and in-depth understanding of the application needs of different industries, the development of targeted technical solutions, these are the current manufacturers in the market competition in the focus.
Stable prices, large capacity/high power orientation
In terms of product prices, due to the maturity of technology and application, the overall price of ultracapacitor products tends to be rational. Some market participants have stated that the current product price reduction range is basically kept within 10% per year. In particular, small-capacity supercapacitor products have basically matured (mainstreaming 0.1F, 0.47F, 1F, etc.), and the products are widely used in tax control machines, solar lawn lamps, wind-solar hybrid street lamps, electronic electric toys, digital photo frames, and smart devices. Meters, energy meters and other fields. At the same time, under the drive of low-carbon, energy-saving and environmental protection policies during the 12th Five-Year Plan period in the country, the supercapacitor market with large capacity (above 100F, even reaching 200,000F) and higher power (such as 8-10KW/kg) is also Is embarking on a track of rapid development.
"In terms of small and mobile consumer electronic products, the price of ultracapacitors shows a trend of gradual stability," said Zhang Xigui, deputy director of the Supercapacitor Engineering Technology Research Center of Shanghai Aowei Technology Development Co., Ltd., "Compared to large-capacity supercapacitors, The price of small ultracapacitors is relatively expensive. The current price is basically 50-100 yuan/kJ. The market prices of large-scale and ultra-large ultracapacitors for automotive applications are also relatively stable, generally in the range of 10-20 yuan/kJ. The fundamental reason lies in the growing market demand for large and ultra-large supercapacitors. In simple terms, this is due to the relationship between supply and demand. At present, most manufacturers in the industry focus on the development of key technologies and core technologies."
According to reports, Aowei Technology is currently building a 100-mu ultra-large supercapacitor production base in Shanghai Nanhui with a capacity of 3.5 million/year and an output value of more than 600 million yuan. The company's key development plans for the future will focus on high-power automotive applications. The manufacture and marketing of supercapacitors and high-performance supercapacitor products, among which, new high-specific-capacity material technologies (graphene and its composites are the most promising), pole piece molding technology, power management technology, test technology and standard formulation, etc. It will be the top priority for development.
In addition, Beijing Jixing United Electronic Technology Co., Ltd. also expanded its supercapacitor production base in Changzhou, Jiangsu Province last year. The new production base can reach an annual output of 3 million super capacitor single product sizes of 100F and its model in Beijing. The group's production base also achieved a new round of investment and construction, and achieved an annual production capacity of 30,000 standard modules and 200 sets of customized large-scale energy storage systems.
New energy vehicles and wind power market highlight new business opportunities
Undoubtedly, at this stage, national policy guidance is still an important driving force for the advancement of the supercapacitor industry. Driven by the national “Twelfth Five-Year Plan” energy and environmental protection policies, new energy vehicles (especially large and medium-sized passenger cars) and wind power industries will become important application markets for large-capacity supercapacitors. According to related data, China Supercapacitors 2013 is forecasted. The market size is expected to be approximately RMB 1.92 billion, and it will increase to RMB 3.3 billion in 2016, with an average annual growth rate of around 20%.
For the recent development trend of the new energy automotive market, Yang Guoqing, currently a deputy general manager and deputy general manager of Shenzhen Times Energy Technology Co., Ltd., analyzed that with the new capacity in the market, the promotion of new energy vehicles in the “Ten cities and 1000 vehicles” has ended. In March this year, the subsidies for new energy buses will be used up in the first half of the year. It is expected that the subsidies for new energy buses will continue to increase in 2013, and the sales of new energy buses will exceed the 5,000 vehicles previously subsidized. On the other hand, in June of this year, the “National Ten Articles” proposed to speed up the elimination of the “Yellow Label Vehicle”. Local governments have also introduced detailed rules to eliminate “Yellow Label Vehicles” within the prescribed time limit. This will create 630,000 vehicles in the next three years. The demand for passenger cars is updated, and new energy buses have become an important passenger car market to fill the gap and one of the development directions.
In the electric starting system of the diesel locomotive, the super capacitor-assisted starting device is used, which has a very high power density, so it can better meet the power demand of the electric vehicle when starting, accelerating, climbing, and if used with the power battery, It can also reduce the damage caused by high current charging and discharging to the battery, prolong the service life of the battery, and has a very high energy recovery rate.
