With the increasing demands for environmental protection, electric vehicles have gradually emerged from as early as this year’s Beijing Auto Show at the occasion, a number of major Chinese and foreign auto companies are displaying their own electric vehicles. In fact, we know that, compared with the conventional fuel energy vehicles, electric vehicles in terms of economic performance and environmental performance has a relatively unique advantages. At present, China has become the world’s largest car market, the market potential of electric vehicles is also very impressive. Therefore, some Chinese and foreign automobile manufacturers had realized this, have to increase investment and research and development efforts, hopes to win market opportunities. But they must be clear, the market facilities are still outstanding level of attainment, which is an important part of concern.

First, development of pure electric vehicles lack a unified standard. There is no uniform standard in the country before the introduction of many research results have a certain “temporary” risk. Here is a simple example, if a depot developed its charging electric vehicles is “plug-in”, that is required after the power runs out to find a socket to recharge, then the size of the interface charge should be? Whether the charging station is equipped with the future of the socket match?

If my electric car is “Battery Type”, and directly replace the battery power runs out you can, without charge, then the problem came again, to be replaced down to how to dispose of old batteries? To know if the battery recall this issue is resolved well, it will generate new emissions and pollution. A small button battery can be about 60 million liters of water pollution, water consumption is equivalent to one’s life. The domestic auto manufacturers to introduce the electric car car battery life is generally about two to three years. If the electric vehicle production, after several years of treatment of waste batteries will inevitably become a new environmental problems. Therefore, the policy has not yet introduced in the standard before the electric car just some of the manufacturers to the name of environmental protection, the development of a “temporary toy.”

Second, the poor infrastructure. In fact, I believe that infrastructure is necessary for the state power grid and related energy sector support. However, when the State Grid Corporation earlier this year proposed to open in 27 cities nationwide electric car charging stations construction planning, the experts also expressed concern: Due to lack of national standards, the practical effect of charging stations will be compromised, may cause a lot of research and development of electric vehicles can not go through the two power charging station for charging.

Therefore, the pure electric car you want to prosper together, needs to rely on countries to develop appropriate policies to promote industrial development, encouraging enterprises to increase R & D of new products and input. In other words, should be unified, “national standard” to promote the development of pure electric vehicle industry, otherwise, at this stage of the manufacturers for their own array of independent research and development can be said to be blind, children had somewhat the feeling of every family.

The last three years, the battery industry in Changxing County, at an average annual market sales of about 100% of the rate of growth of production and technological level of enterprises increased year by year, product areas from expanding batteries for electric bikes to the new energy sector. Last year, Changxing County, was appraised as “China’s New Energy and Industrial hundred counties” and the national green power energy high-tech industrial base, was the first province of Zhejiang Provincial Government as a massive economic transformation and upgrading of 21 one demonstration area. Behind these achievements is the scientific and technological innovation into full play.

Government is actively promoting cooperate with universities to encourage independent innovation. In recent years, Changxing County in-depth implementation of the “in-depth views on promoting the implementation through Cooperative”, Changxing county government, the county held an annual technology conference organization, organization to promote research cooperation project for more than 100. Meanwhile, the Changxing County launched the “Changxing County, to speed up scientific and technological innovation on a number of policy advice,” such as science and technology policies to encourage enterprises to increase the scientific and technological innovation. Battery industry through Cooperative projects throughout the county in 2008 and 2009, respectively 24 and 23. With the accelerated pace through Cooperative, Changxing battery technology company in a strong backing of Chan Xueyan under the growing capacity of independent innovation, greatly accelerated the process of transformation and upgrade the battery industry.

Battery industry bigger and stronger technology platform. On the one hand, with the battery companies to deepen awareness of independent innovation, enterprises continue to increase R & D and actively with universities, research institutes co-build a research center for the battery industry to provide a strong scientific and technological support. Among them, the days to the Group and the Space Department, Zhejiang University, Fudan University, Zhejiang University of Technology established a provincial-level enterprises and other cooperative research and development centers, the provincial post-doctoral research station; Chao Wei Power Co. and Tsinghua University, Shenyang battery Institute, environmentally friendly batteries established research centers at the provincial level high-tech enterprises, the provincial post-doctoral research station, and Fuzhou University jointly established the “Fuzhou University - Ultra-high-tech R & D Center Gateway company.” On the other hand, the Government to strengthen guidance and accelerating technological innovation in public service platform. Changxing County last year, build a “Green Power Energy, Zhejiang Province, integrated innovation of public service platform”, the Centre in accordance with international and domestic types of standards, lithium battery, nickel hydrogen batteries, solar cells, raw materials and more than 90% of new energy projects , have seized bearing capacity.

Currently, Changxing County, battery industry has been formed from raw material processing, plate production, parts manufacturing, assembly, sales, to waste battery recycling industry chain, to become the county’s industrial economy a major pillar industry, “days to “,” super-Wei “as the battery industry cluster of leading enterprises in Zhejiang Province and even China has become an influential block of new features regional economic clusters. Last year, Changxing County, a total of 55 battery manufacturers, including six high-tech enterprises, the county battery industry accounted for 50% domestic market share of about regulations on the production of battery companies completed a total of 14.15 million KVAH (about 12AH battery 98 million) , sales revenue of 4.19 billion yuan in 2006 rose to 12.67 billion yuan, average annual growth of 44.6%, accounting for county regulation on the industry’s 27.3%.

Changxing County Technology Department official said, Changxing County, the battery industry is poised to thrive, and actively respond to the county government’s “two-year span, another brilliant innovation,” the overall goal, with the power of technology, through technological innovation, and strive through 2-3 years of efforts to achieve the battery and the New Energy and Industrial output value of 50 billion yuan, sales income Chaobai Yi Enterprise 3, built up significant new energy R & D, manufacturing base and industrial development Heights, the battery and create a new energy industry as a province and the country strategic industry clusters, industry clusters to achieve the transformation to a modern upgrade.

When the oil is exhausted, it hopes electric car, hope it can protect the environment, re-energize the community. Experiments show that electric vehicles can meet people’s expectations, and find the perfect cell program has been the focus of researchers.

If you can really achieve by 2030 the German national development plans electric vehicle scene depicted - Germany has five million electric cars on the street driving - let us look back. In the internal combustion engine vehicle was born 30 years ago, electric vehicles already on the road, and create a considerable speed record: 1899 Belgian Camille Jenatzy driving their own vehicles manufactured, faster than 100 km per hour. Turn of the century, power has emerged in New York taxi fleet. However, due to failure to continue to provide power for the electric vehicle battery program, its development has long been stagnant.

Compared with the internal combustion engine to power as the driving force of the advantages are obvious: start accelerating fast, power up to 3-4 times, driving noise, and does not require driver installation. However, the shortcomings of electric vehicles also exist, one important point is that power always be quickly consumed.

From a global point of view, regarded researchers and developers focus on batteries, lithium-ion battery technology represent the current level of research. The early nineties, Sony produced the first small lithium-ion batteries, due to its high performance, long life and short charging time, quickly in small devices such as mobile phones, notebook computers and other aspects of model aircraft have been application. In the automotive field, initially no one is willing to use lithium-ion batteries, lithium as electrode materials will not only lead to voltage too high, and very easily with other elements of the reaction.

In the notebook computer, even if the battery has a slight injury, and only in extremely high temperatures and under high voltage charge would result in the loss of the battery elements into the air, causing the computer on fire. However, the German state of Baden Fraunhofer Institute of Chemical Technology pfinztal battery researcher Jens Tübke said: “The car was completely different.” Motor vehicle battery to store very much energy, it can even turn into a bomb. In the laboratory, and factories, single voltage below 3.6 volts, it will change once the short circuit and thermal expansion, in the finished battery has a lot of a single voltage, in such a huge energy density conditions, even the light touch, the consequences would be unthinkable.

For users, it is important to recognize that which is more useful in terms of their own.

Security: Würzburg Department of Fraunhofer Institute for Silicate Research Fellow Kai-Christian M? Ller have tried to use non-flammable combustible liquid polymer to replace the battery, but the electrode will be affected by the impact of gelatinous plastic, charging time extension can not be achieved excellent performance.

Saxon joint venture Li-Tec, tried other ways to address these security issues. In general, battery manufacturers use a thin plastic membrane separating the two electrodes, but when the temperature reaches 140 degrees Celsius, they will be the same as the bottom panel of plastic melting, easy to cause a short circuit. Li-Tec ceramic particles used as a membrane coating that can withstand 700 degrees Celsius, but the battery power is decreased. On the other hand say that this battery charge and discharge will not be scrapped after 4000, which requires daily recharging electric cars is very important. Li-Tec Corporation will next year launch of this car is safe and durable batteries.

Durability: Lithiumtitanat company can be made with great battery charge and discharge at least 15,000 times (2000 times operator excellent value). The battery life of up to ten years in the medical equipment in the well of the application, the medical technology of great value.

Discharge capacity: If you want to store in a small space more energy, can electrode adding Iwo. In theory, Iwo to three times more than conventional polymer electrode of lithium ion. In the laboratory, this approach may seem bright future, but discharge only 20 to 40 times, after almost can not be used again.

Fast Charge: If you want to fast charge, iron phosphate electrode materials for good results. This case, cell phone batteries in 20 seconds is charged - at least in the laboratory is the case, but needs a lot of power.

Car battery safety, discharge capacity and durability are interrelated, the consumer he rose, and battery manufacturers into a dilemma, one aspect of increased mostly at the expense of other aspects of the cost. Pfinztal battery expert Tübke said: “Fortunately, lithium ion system there is great room for improvement.”

For electric vehicle battery to use gasoline or diesel class transport driving range, and the safe and economic, for the time being or can not be achieved, the metal-air battery as well. In the metal-air battery, oxygen in the air was as lithium reactants. IBM researchers Chandrasekhar Narayan said: “This battery is like a burning engine. Is now breathing air vehicles with gasoline and burning it in the future be used for electrochemical reaction of air.” IBM hopes to use this way to make Electric Vehicle mileage of 800 kilometers - more than current lithium-ion battery far more than 10 times. IBM is expected to produce in five years the first sample, while other researchers are expected to be extremely careful in this research program requires time-consuming for decades.

Finally, we discuss an old program, which was originally designed for the stationary energy storage device: not to charge the battery, but the fuel. In redox flow battery technologies, energy is not stored in the electrodes, but stored in the battery liquid electrolyte. Redox Technology now small capacitance. Fraunhofer-Institut, Institute of Jens Noack new technology sector, said: “We have succeeded in the efficiency of its range increased to 4-5 times, it had followed very similar to the lithium-ion batteries.”

This, Tübke excited and worried: “The idea of the very dramatic, but in the next 20 years or 30 years, also
Can not solve our difficulties. “

New energy, industry, an important part of transition, from the previous year the number of waves has been speculation that the concept of its range, from solar energy, wind energy to nuclear energy, from automobiles to batteries, and new energy seemed linked.

    In fact, the new energy is the key energy storage technologies, such as electric vehicles, the biggest problem is charging, now push the business model is to create “add station” to replace the battery to solve. If you can find a “super capacitor” can solve the problem. Because of this, the concept of new energy speculation to the present, “Super capacitor” as those who come from behind.

    Promotion of new energy vehicles, or as an opportunity to

    The so-called super capacitor, is a new energy storage device, due to its energy storage process is reversible, so you can repeatedly charge and discharge hundreds of thousands of times, with the power density, high capacity, long life, maintenance-free, economic, environmental and so on.

    At present, the super capacitor is mainly used in five aspects, including the tax control machines, digital cameras, PDAs and other small current back-up power supply; intelligent table (smart meters) for solenoid valve power supply startup; beacon lights, solar products, instead of rechargeable batteries; small rechargeable batteries instead of rechargeable products, and electric toys and other small-power electric motor drive power supply.

    The future, the super capacitor in the car (especially electric vehicles, hybrid fuel vehicles and special load vehicles), rail, consumer electronics products, has a great value and market potential, they have been around the world have received extensive attention.

    Early last month, China’s purchase of new energy vehicles for private financial subsidies formal introduction of the new policy options in Shanghai, Shenzhen and other cities as 5 start private purchase of new energy vehicles to subsidize pilot, plug-in hybrid vehicle the maximum subsidy per 5 million; pure electric passenger vehicles the maximum subsidy per 60,000 yuan. Market participants pointed out that this will be the opportunity to further develop super capacitors. Find the material is the key

    Super Capacitor, one of the most important thing is to find the material used. Previously, the industry’s hot, lithium ion battery to replace lead-acid batteries, nickel metal hydride batteries, but one made by a super-high-purity barium titanate capacitors, but may overturn the lithium-ion battery.

    Data indicate that the current car battery mainly in the following four categories: lead-acid batteries for most low-grade, heavy pollution, currently only for battery cycling. Low profile for the Ni-MH battery, characterized by expensive, driving is very short, not the future of electric vehicles. Even the best thing is that lithium iron phosphate batteries, more expensive, the current Shenzhen BYD electric cars have been used, and to achieve a charge traveling 100 ~ 120km. Need to start the gasoline engine to extend the mileage of a hybrid, but the security risks. The best is the super-capacitor battery, cheap, maintenance-free, 10 to 50 million charge and discharge cycle life, will become the main power battery.

    It is understood that the manufacture of super high purity barium titanate capacitors, and nickel-hydrogen batteries / lithium iron phosphate battery, compared with the energy density, energy efficiency, safe, cheap and other advantages.

    Analysts pointed out that the super-capacitor on the downstream industry will be the Government’s strong support. Its use determines its strategic value, the world’s major countries are putting in a lot of manpower and resources to research and development. With the deepening of economic restructuring, the Government will eventually find their value, and the introduction of a strong industrial support policies to promote the strategic product development of upstream and downstream industry chain.

Buy low, sell the opportunity has arrived

    Days with investment that investment super-capacitor

    Industry, the main focus on three, one, super capacitor industry still in its infancy, but is much room for future development; 2, super capacitor applications will focus on the main traffic areas and smart grid in the area of technical barriers to its relatively high , is expected to be over-income; 3, super capacitor application in the field of industrial equipment has some space, but essentially is based on the projects, the benefit of the company will be super-capacitor-based electrical control system segments.

    Supercapacitors basic upstream and downstream industries as follows: Terminal application industry, super capacitor system, super capacitor electric control system, super capacitor, electrode, electrolyte, separator.

    The current A-share listed companies, Farah E [21.75 -5.52%], copper peak electron [6.09 -1.46%], Shenzhen Hui Cheng, the new state-chou, Fosugufen [11.08 -1.95%], big Southeast [6.87 -0.87 %], Nanyang Technological [59.58 -1.55%], Kane shares [11.86 -0.50%], Ankai car, Dawn shares [12.29 -1.52%], Golden Dragon Auto [6.41 -1.08%], etc., related to super-capacitor upstream and downstream industries.

    Strategies specific to the operation, 3 months to May this year, there have been a wave of speculation super capacitor, such as Farah E, in less than two months time, or nearly doubled, from 15 yuan rose to nearly 30. However, after nearly two months of decline, the sector has returned to a reasonable valuation range, the new Energy is a pillar industry in transition, I believe will perform well, investors can wait for the opportunity to bargain involved.

David Ryder to demonstrate a non-sealed plastic solar cells. Photo and caption from the University of Alberta University of Alberta and nanotechnology research institute, found a way to non-sealed plastic solar battery life to eight months of the method.

Functional plastic solar cells could become the next generation of solar photovoltaic products such as fabrics, of a transitional product, also allows better integration of optoelectronics into building materials.

A university chemistry researcher Daiweilaide said: “cheap, lightweight plastic solar cell products, can be rolled up like a blanket or paper, which will change the solar industry.”

However, a stumbling block for the development of plastic solar cells is their limited operational life, usually only last for just a few hours.

This matter relates to electrodes, this is one of the solar cells can efficiently extract the important electrical circuit.

Mr. Ryder said: “A typical suction electrode coating is considered unstable, it can migrate through the circuit to limit our battery for about 10 hours.”

To overcome this obstacle, the researchers developed a new polymer coating, can be compared with the original design of durable 5000%. When the team presented the findings to scientific journals, the new battery already has 500 hours of working time.

However, solar cells shipped back to Ottawa in additional damage to the test. However, Mr. Ryder said that if it is not broken, then solar cells will be able to operate at high capacity.

Although the team won the world team success and progress, Mr. Rider that more research is needed to make plastic solar cell tool came home improvement store shelves.

He explained: “We must improve efficiency, while maintaining its long-term steady growth. Get eight months of high-capacity performance has Confirm our design going in the right direction.”
