With the rapid development of battery technology vanadium, vanadium battery will bring an unprecedented human and significance of far-reaching new energy industry revolution!

Advantages of vanadium battery

Compared with other chemical power, vanadium battery has obvious advantages, the main advantages are as follows:

1. Power is big: by increasing the number of single cell and the electrode area, to increase the vanadium battery power, the U.S. commercial demonstration run of the vanadium battery power has reached 6 MW.
2. Capacity: through any increase in the volume of electrolyte can arbitrarily increase the vanadium battery can be Da Jiwa over time; by increasing the concentration of electrolyte, you can multiply vanadium battery.
3. Efficiency: As the vanadium battery electrode catalytic activity, and positive and negative active material are stored in the positive and negative electrolyte storage tank, to avoid the positive and negative electrode active material consumption of the self-discharge, vanadium battery charge and discharge energy conversion efficiency above 75%, much higher than 45% of lead-acid batteries.
4. Long life: As the vanadium battery positive and negative active material only exists in the positive and negative electrolytes, charge and discharge the battery when no other common phase change, can not damage deep discharge battery, battery life . Canada VRBPowerSystems currently the longest running commercial demonstration of the vanadium battery module has been running more than 9 years, the charge-discharge cycle life of more than 18,000 times, much higher than the fixed-type lead-acid batteries 1000.
5. Response speed: the heap is full of vanadium battery electrolyte can be instant start, the operation process of charging and discharging state switch just 0.02 seconds, the response speed of 1 ms.

9. Vanadium battery location large degree of freedom can be fully automatic closed operation, no pollution, easy maintenance, low operating costs.
Vanadium battery market prospects
Vanadium battery market in China and the world are shown in Table 1, Table 2, in which wind power and photovoltaic power generation needs of the vanadium battery market based on total installed capacity (see Table 3 ~ 6) 25%, the other areas of the vanadium battery market demand by 100 % calculation; vanadium battery output to 20,000 yuan / kW basis, non-electrolyte.
Wind Power
Wind power generator with the current needs of approximately 1% of its power lead-acid batteries used in emergency situations receive fan blades protected with the other needs of each wind turbine is equipped with power equivalent to about 4% of its power back-up batteries. As power has become a bottleneck in the development of wind power, with the explosive growth of wind power, wind power and power conflicts will become more prominent, in order to reduce the impact on power, greatly improve the utilization of wind power while making peak power to take the huge price difference, the wind farm will be equipped with power equivalent to the power 10 to 50% of the dynamic storage batteries. For the fans off-grid power generation, you need a larger proportion of dynamic storage batteries.
As fans there is now lead-acid batteries used in small capacity, short life, poor stability, maintenance time and effort, causing pollution and other serious defects, fan manufacturers have been looking for a better alternative to lead-acid battery products, I believe has many outstanding advantages The vanadium battery can replace the existing lead-acid batteries, wind farms and then build the dynamic energy storage systems, greatly improve the efficiency and effectiveness of wind farms, wind power industry to promote better and faster development.

PV

According to authoritative statistics, in recent years the average annual growth rate of the global PV modules up to 30%, the photovoltaic industry has become the fastest growing new industries. Particular, in 2008, the global total installed capacity of photovoltaic power generation to 3 GW.

As the name implies, solar photovoltaic power generation needs, once in the evening and rainy day could not send the electricity, which requires storage batteries for electricity, due to lead-acid battery power, capacity and life are very limited, I believe many outstanding advantages in a set of vanadium Photovoltaic cells will serve as the preferred energy storage battery.

Peaking power

Peaking power has been the primary means of pumped storage power station. Nearly three decades, the development of pumped storage power station developed countries more and more rapidly. Pumped storage power station in the world's fastest-growing, Japan had the largest installed capacity, followed by the United States, Italy, Germany, France, Spain, Japan and the U.S. pumped storage power station have been more than 20 million kilowatts installed capacity.

Pumped storage power station to be built because the upper and lower reservoirs, subject to more limited geographical conditions, in the plain areas is not easy to build, and covers an area of large, high maintenance costs. Vanadium battery storage power station from the geographical conditions, location free, small footprint, low maintenance cost. Can be expected, as the vanadium battery technology, vanadium battery storage power station will gradually replace the pumped storage power station in the network play an important role in peak shaving.

Traffic Services

As the world continues to accelerate the urbanization process and the continued increase in car ownership, car exhaust pollution has become the number one source of urban air pollution. Vigorously develop energy-saving, environmentally friendly alternative to traditional fuel vehicles electric vehicles, has become the consensus. With the rapid development of vanadium battery technology can be expected, has many outstanding advantages of the vanadium battery in electric vehicles (especially the urban bus), electric scooters, electric bicycles, electric ships, traffic signals, solar hybrid street lighting, etc. to play broad field important role.
Communication base station

Base stations and communication needs of the battery as a backup power supply room, and usually not less than 10 hours. Operators in terms of communications, security, stability and reliability and service life are the most important in this area, vanadium battery has a lead-acid batteries can not match the inherent advantages.

UPS Power Supply

CCID Consulting's research shows that in 2007 UPS market in the continued growth trend, mainly due to sustained and rapid development of China's economy brought about by decentralization of UPS user needs, making the industry more and more enterprises have sustained UPS needs. The next few years, UPS product development direction is higher availability, security and features integrated, intelligent and humane.
Currently, China's UPS market, strong demand for power, security, stability and reliable batteries, vanadium redox battery in this area, as opposed to lead-acid batteries in terms of power, security and stability, or life, both have an absolute advantage.

Power Distribution

Today's society on energy and electricity supply quality, efficiency, environmental protection and the security and reliability of increasingly high demand for large power grids due to their own shortcomings can not meet this requirement. With the rise of power distribution, large central power stations will gradually decline. Vanadium battery that will be the first in the hospital, command and control centers, data processing and communications centers, commercial buildings, entertainment centers, vital government departments, pharmaceutical and chemical materials industry, precision manufacturing industries play an important role in the distribution of power.

Military Reserve Power

Vanadium battery can also military bases, command centers, military and other military departments play an important role in charge storage.

Arouse dreams of green biofuels flight

10, Continental Airlines announced here, the first commercial aircraft flight using biofuels recent successful test flight. It opened in 2009, including China, a series of new tests of fuel off the aircraft, once again aroused the people to take the green air travel dreams.

Fuel: Jatropha tree with seaweed extracts and flight

Continental Airlines Beijing office to provide information to reporters, said the plane did not carry passengers on the Boeing 737-800 aircraft for about two hours of successful flight. Continental Airlines Chairman and CEO Luokai Rui said: "Through this test the technical knowledge gained will help to more deeply explore the sustainable development of air transport fuel future."

According to Continental Airlines Chief Representative of China and director of Guoxing Chang introduced to compare the use of biofuels and conventional fuels mixed performance, flight test aircraft No. 1 engine of 100% using the traditional jet fuel, No. 2 engine uses 50% of the extract of Jatropha curcas and algae 50% biofuel with traditional jet fuel. This mixed bio-fuels will greatly reduce carbon emissions. Jatropha curcas and algae in their life cycle can consume a lot of carbon.

Despite the sharp decline in global oil prices in early 2009, but in the long run, to reduce oil dependence, reduce costs and achieve air emission reductions, the new fuel by the way the aircraft is a must. In addition to Continental Airlines, New Zealand, Brazil and other countries are carrying out bio-energy aviation flight experiment.

Bio-energy use, inevitably raises concern for food security. In this regard, Luo Kairui said, and the extraction of fuel from corn and other grains is different from seaweed extract mixed with Jatropha curcas on food crops or biofuels will not adversely affect the water supply can also reduce deforestation.

Do not burn oil aircraft: new technologies need to overcome the revolution

International Air Transport Association recently announced in Beijing, the world's first prototype solar-powered aircraft will conduct the first test flight in early 2009 and is expected to arrive in China within the next two years.

And the mixed fuel of different aircraft, the aircraft does not use solar energy vehicle oil. Bisignani said IATA director, the world's first solar-powered aircraft earlier this year after a first test flight is expected in 2011 to fly around the world including China.

Boeing, one with a proton exchange membrane fuel cell and lithium-ion batteries for small manned plane, successfully conducted its first test flight last year. Driven by a pilot of the aircraft, relying on battery power at 1000 m altitude of 100 kilometers an hour flight for about 20 minutes.

According to reports, China's Trina Solar Company and Air France jointly developed by Lisa new energy powered aircraft is also expected to complete the assembly of the end of 2009. This will be the world's first solar and hydrogen energy to power the new aircraft.

China Dream: energy saving and technological innovation

International aviation community believe that the use of aircraft fuel mix is expected to put into commercial operation next 5 years. Totally ordinary passengers to take the new aircraft burning oil, it may take 20 years or so.

"We hope that the new fuel mix of aircraft operating in the China-US route as soon as possible, the sooner the better." Continental Airlines Chairman and CEO Luorui Kai said.

In recent years, IATA has been working to promote the reduction of carbon in the air and plans. After the United States as air power and the world's second largest consumer market of aircraft, aircraft fuel in China is facing new challenges in research and development.

At present, the total cost of airline fuel costs 36% to 40%, if the new fuel, can effectively reduce aircraft operating costs and reduce greenhouse gas emissions.

IATA's airline industry in the zero-emission process, the investment in new technology in a key position. It is reported that China's current development of biofuels has certain technical advantages, but in non-traditional powered flight is far behind Europe and America.

337 battery patent dispute

Chinese battery companies win in U.S. patent disputes Energizer

Chinese battery company jointly responding to victory over the United States Energizer "337 battery patent dispute case", as Chinese enterprises overseas rights of another example. The results of the victory is important, but the lessons learned for process analysis and continue to "go out" of Chinese companies may be more beneficial.

Unity is strength

Since 2002, China has suffered for 6 years as the United States "337 investigation" the most involved country, by the "337 investigation" of the company is involved in electronics, light industry, chemical, biological, medical device and other industries. But now, responding to China's enterprises, "Section 337" less than ideal circumstances.

During the "337 battery patent dispute case" in the lead by the China Battery Industry Association, the Chinese respondent companies have weathered numerous challenges, and always adhere to the group operations, the industry has not yet have a product exports to the U.S. companies are generous. Chinese respondent enterprises in Fujian Nanping Nanfu Battery Co., Ltd. Administration Department Kangjin Wei recalled: "the meeting in Ningbo, a home out of non-respondent enterprises on the spot 4 million to support the respondent, which is a kind of national spirit."

"Battery Battery Company in favor of '337 patent dispute 'a great inspiration to domestic enterprises." Deputy director of Intellectual Property Academy of Social Sciences Li Shunde, said in an interview, the respondent on the one hand argue to have the courage and the attitude of scientific analysis, to positive response, and dare the respondent, good responding, we can not blindly believe in each other's conclusions can not be negative patient, show a sufficient basis to reasoning; the other hand, the respondent to pay attention to strategy, responding to need money, manpower, resources, legal and other aspects of support, individual companies may weak, but we unite together, through trade associations and other intermediary organizations to win only the possibility of coordination. Particularly in the face of the United States "Section 337" may give the "general exclusion order", responding to the results will affect the development of all enterprises in the Chinese industry, this requires the joint efforts of the entire industry.

Preventive measures

Energizer in the United States on the outcome of litigation lost, but Kang Jinwei, the U.S. companies the importance of intellectual property, but domestic companies should learn. Compared with the Energizer, domestic enterprises lagged behind awareness of intellectual property, ability to use intellectual property is obviously lacking. Kangjin Wei admitted, the defendant after the company realized the importance of patents, patent applications began to study. Nanfu company as the industry's leading enterprise like this, other companies can be seen.

At present, awareness of intellectual property rights of enterprises are generally not strong, resulting in some enterprises, especially exporters exist in varying degrees, the risk of infringement of foreign intellectual property. Wang Jing Zhong of China Battery Industry Association, said the Secretary-General, the enterprise should have a strong awareness of intellectual property, we must understand the situation of the enterprise intellectual property, product development at the same time make sure to do the work of the patent application, so as to really protect their own interests from damage. "337 battery patent dispute," the Chinese firm attorney Stephen Hawking? Stockhausen law firm Zou Guorong are suggestions that Chinese enterprises "going out", be sure to understand the target market, distribution and protection of patents, know ourselves, can prevent the first place.

Enhancing strength is the key

United States International Trade Commission 709 final award decision Energizer patent for its failure to meet U.S. federal patent law described in section 112 of the written request is invalid, mainly due to the uncertainty of China's terms of use patents against other patents. Previously, the 709 was the Energizer patent to the United States, Japan, Singapore and many other battery companies collect royalties for the "killer." According to Zou Guorong said, it is generally believed that the U.S. patent is very strict, patent litigation is usually from the patent novelty and significance of this relatively easy to prove two points to start, very few people with the uncertainty of patent terms. "This is based on our deep understanding of the United States based on patent law, and it is the key to our victory."

"Enhancing strength is the key." Wang Jing Zhong said that mercury-free alkaline manganese battery technology is now very mature, domestic enterprises should be in the new energy batteries such as lithium batteries, etc. to speed up R & D, do the layout and development of intellectual property. It is understood, Changhong Group is currently working on a new generation of digital product development for high-power battery to actively apply for patents. Reporter also learned that quite a few battery companies have to improve their core technology R & D capabilities on the agenda, step by step to innovative projects, the concrete implementation of the work to each quarter, every month.

New Flexible Solar Cell

Recently, U.S. scientists have found an effective way of making silicon solar cells with sufficient flexibility, which allows it to wrap the object in the thickness of a pencil on top of or attached to the windows of buildings and even cars glass surface. October 5 issue of the "natural materials" magazine reported the results, saying the technology can be easily broken before the transfer to the flexible material on top of silicon, silicon slices for the traditional process provides new possibilities .

Of the study, University of Illinois at Urbana-Champaign, John Rogers, said the new technology will open the door to the promotion of solar buildings, "we can make it thin enough, then 'transfer' in a plastic chip, which to be curled into the system, so similar to the film thickness of the film can be attached to the glass surface of the building. "

It is understood that due to global warming and the impact of high oil prices, relying on photoelectric conversion of solar cells known as one of the most promising green energy. Including Japanese consumer electronics maker Sharp and Q-Cells of Germany, including many companies are making thin-film solar cell research and development related areas. But compared to conventional solar cells, thin film photovoltaic solar cell conversion efficiency lower the industry has been plagued problems.

Rogers said the technology is based on a higher photoelectric conversion efficiency of silicon as a raw material. Monocrystalline silicon wafers in order to overcome the shortcomings of a very brittle friable, they used a special etching method of silicon from a large cut on the silicon than the traditional 10 to 100 times thinner ultra-thin silicon . Different levels according to their thickness can be applied to different areas. When the wafers are cutting down, it will be a device to pick up, and then sealed as the general "transfer" to a new material above the surface. Finally, the re-use these as the electrical system of solar cells together into a whole. Compared with traditional solar panels, highly flexible solar cells that will be easier to transport and install. And Rogers is envisaged that the new materials will be like a blanket was thrown on the car.

The Diamond Consortium is to enhance a finding errors in the chip development. This should reduce the development costs long term. The EU provides subsidies.

Then, my friends blog: Battery Hair, Discount Batteries, Penta Win, Gitablyp Say, Ratrol Cup, etc.

IBM wants to get together, according to a press release with companies and universities in the European Union in order to improve the reliability and efficiency of semiconductor chips. The EU-funded organization called Diamond Consortium. The project has a timeframe of three years.

An objective of the Diamond project is to work together to find a more systematic approach to search for chip defects. Currently, 70 percent of the work in the development of a chip inserted into the debugging, says IBM. The majority of them will invest in order to find the error and correct it.

¡°Soft errors¡± are particularly difficult to find and predict. This type of transient malfunction creeps by external factors. An example of one such factor is the cosmic radiation. Their effects are greater, the smaller and denser, the chips are mounted.

From the new technology is expected to IBM engineers, such soft errors can be predicted better. These are special use improved detection methods, which could reduce the time to eliminate these types of errors by 23 percent.

Error found in chips and correct costs to the producers in this year 34.5 million U.S. dollars (25.4 million), expects IBM. The Diamond Consortium is hoping to reduce the time for debugging by half. On the cost side, could theoretically bring a savings of 17.25 million U.S. dollars (12.72 million euros).

Besides IBM take on Diamond Project Ericsson, part of the Tallinn University of Technology, the Swedish Linkoping University, the University of Bremen, the Technical University in Graz, TransEDA system from Hungary and TestonicaLab from Estonia.
