In advanced energy technology "twelfth five-year" 863 plan "high performance chemical energy storage battery key technology research and demonstration plants" theme projects, supported by "can ratio, low cost of the new super capacitor is a key technology research" subject made major progress, recently passed technical acceptance.
From the ministry of science and technology official weibo "sharp technology" on August 15, in terms of "new super capacitor", break through the high energy density, high power density, long life of super capacitor preparation technology bottlenecks, developed a porous graphene, high pressure and electrolyte salts and electrolyte, such as cellulose membrane materials, developed a dry preparation of electrodes pilot technology, break through the (3.0 V / 12000 f) at the heart of the supercapacitor industrialization technology, products have been in the mechanical energy recovery, super capacitor, both at home and abroad get applications for railway vehicles.
Reported that at present domestic in the aspect of super capacitor from material and devices to the system integration has become the core technology system, changed the super capacitor during the period of "11th five-year plan" monopoly by foreign products.
Ultracapacitors new breakthrough to break the level of foreign products monopoly potential demand will amount to billions
The state shall pay attention to the development of
Super capacity battery, also called gold capacitors, farad capacitors, energy storage by using polarization electrolyte, belongs to a kind of electric double layer capacitor. Because of the energy storage process does not produce chemical reaction, so the energy storage process is reversible, because of this super capacitor can be repeated charge and discharge hundreds of thousands of times. Ultracapacitors generally use activated carbon electrode materials, has a large area of absorption, electrostatic store more characteristics, are widely used in the new energy vehicles.

The government has always attached importance to in the development of super capacitor. In 2006, 2007, in the technical aspect emphasized the importance to the development of super capacitor, after the government introduced a subsidy policy for supercapacitor applications.
In 2016 as the start of the implementation of "much starker choices-and graver consequences-in", frequent good news about super capacitor.
In April, the ministry issued the "strong industrial base, 2016 special action implementation ”Ú case, focus on super capacitor on support for the first time.
Then, super capacitor with organic electrolyte code validation will passed the national industry standard, this standard is the super capacitor materials of the first industry standard, is helpful to the standardization of the super capacitor electrolyte, promote technological progress in China's super capacitor industry.
Followed by miit announcement in 2016, issued including materials, machinery industry, automobile industry, electronics industry, 587 industry standards. Among them, including the classification and super capacitor model named method electronics industry standards. According to information, the standard is carried out formally since September 1, is China's first basic standard in the field of super capacitor.
In the national development and reform commission, the national energy administration issued by the revolutionary energy technology innovation action plan (2016-2030) "and" energy technology revolution action roadmap for focus on innovation, also put forward the development of large capacity of the super capacitor energy storage technology.
In action roadmap for energy technology revolution focus on innovation, puts forward the specific goals for,
Develop new electrode material, electrolyte materials and super capacitor is a new system. To develop high performance of macro preparation of graphene and its composites, to explore the role of the relationship between the structure and the properties of the material;
Developing a new type of super capacitor based on sodium ion system. The positive and negative electrode preparation technology, high-energy hybrid super capacitor is negative capacity matching technology;
R&d 30 wh/kg energy density and power density of 5000 w/kg long cycle life monomer super capacitor technology. Research on supercapacitors modular technology, the breakthrough large capacity super capacitor series parallel group technology. Study of 10 mw grade super capacitor energy storage device key technology, system integration application in large capacity of the super capacitor in braking energy recycling, improve power quality and power system stability control design and integration technology. "
Wide prospect of market
It is understood that foreign research started relatively early, super capacitor technology is relatively mature, is in the lead. American USMSC plan, Japanese and European PNGU NewSunshine plan are developed super capacitor in content.
Globally, 2015 super capacitor in the world market is worth $17.3 billion. According to Navigant forecasts, from 2014 to 2023, the super capacitor market will grow about 20 times average annual compound growth rate of 39%, visible super capacitor market potential is tremendous.
Learn from shen wan hongyuan, super capacitor application field widely, the wind power generation, electric tools and weapons, and other fields has a broad development prospects, especially in the part of the application scenario has very big advantage. In addition, the lithium battery and super capacitor combination will greatly improve the performance of the new energy vehicles, is conducive to further promote the development of new energy automobile market. According to the calculation, factors such as the electric car sales volume and energy storage development, driven by the potential demand of the super capacitor will amount to billions level.
