History of vanadium battery

If, today, as an inquiry into the street and he met someone who does not know the battery is a fairly unusual things, but if the meeting is sure to know someone vanadium Sony VGP-BPS9A Sony VGP-BPS9A/B battery, then this is a very unusual things.

 

It is said about the past and the bar of the vanadium battery.

 

Speaking of vanadium battery of the past, Americans could not help but feel the level of technological development and capabilities. Flow cell (redox flow cell) also known as battery Redox flow, is actually first proposed by the National Aeronautics and Space Administration (NASA) to support the development together, and in 1974 by a person called Thaller published and filed a patent application. This can be seen that the vanadium battery Past and bar.

 

Only specific to this type of flow battery cells, which also includes a variety of specific measures, such as cell redox flow vanadium (VRB), Fe-Cr redox flow batteries, sodium polysulfide battery flows of redox flow batteries lead. Another popular time in the inner circle of the PA3451U-1BRS PA3399U-1BAS battery Zinc bromine flow battery actually counted and a half. The specific principles of presentations online, do not write 啦. If you want to understand, there is a chance it can go to ask questions about Yang Yusheng academician, he has the whole system more comprehensive understanding, the other by Professor Zhang Huamin Dahua also studied, including cells of flow polysulfide vanadium battery (perhaps Professor Zhang has also studied other redox flow batteries).  

 

And then the advent of the vanadium battery is received.

 

According to the concept of flow battery was introduced about 10 years later, in Australia, Professor Maria began studying the use of vanadyl sulfate do positive and negative electrolytes, and in 1986 a patent application. This is considered the true birth of the vanadium battery.   

 

The concept of the vanadium battery really attractive, ah yes, the more attractive because of the negative of the same material, so there is no other type of flow cell of the meeting between the positive and problem negative pollution, maintaining battery theory live longer. Indeed, if no accident, the electrolyte can be a permanent use, and replacing the GD761 KD476 battery and other components can extend the battery life.

 

Then talk about the development of vanadium batteries.

 

Professor Miller said later patent applications Maria such a tempting prospect naturally attracted many companies. Then there is the story of some of Liaoluan and detailed information abroad, I remember there was a buddy wrote a very detailed, detailed to me are not all in memory of brothers who are interested can try Find online to see (remember to notify me found). Probably the situation is the following: Pinnacle Sanxialiangxia Maria received a very low price the patent Aunt Maria Pinnacle company, but soon found their Daoxing also too easy, vanadium battery is also far from being mere imagination, Pinnacle development, not able manufacture products, a Japanese company (forgot the name) at the time of vanadium battery is also very interested, and have therefore received permission from Pinnacle, and began, in May is determined not large enough, may be for any reason, no other product to a battery of vanadium, the company still patent license to Japan’s Sumitomo (SEI). The vanadium battery time has finally found the first being the master of the children of 8, SEI is doing more than 10 years, has invested about 80 million U.S. Oh, and finally, step by step, from 1996 to 100KW system , so that by 2004 4WM System. Next on the things that VRB Power Corporation, Beijing, China acquire VRB Power & Poor’s can do and it is now more and more domestic companies to do things in the vanadium battery.

The international financial crisis accelerates the rise of solar cell industry

For the Global Financial Crisis, the Global semiconductor and electronics slowdown in consumption in the industry. Sony VGP-BPS9 Sony VGP-BPS9/B Among them, the industry of semiconductors, annual sales revenue fell 2.8%, the size of the industry of consumer electronics grew by only 0.94%, the growth rate down 5.5 percentage points. However, the global industry of solar cells has been renewed for five years of dynamic growth rates, output continued to grow substantially.

 

World solar cell to increase production capacity by 83% over 2007, reaching 13GW; production of solar cells increased 35% to 4725MW; PV installation growth of 35% over the previous year reaching 3962MW; solar cell market to reach 15.9 billion U.S. dollars. In solar cell applications, the installed capacity of solar cells in 2008 Europe accounted for 75% of installed capacity worldwide, including Germany occupied the installed capacity in the world more than 50%. Over the past 15 years, the global PV industry with 25% annual growth rate through rapid growth.

 

The solar photovoltaic industry has been able to maintain the momentum of high growth, partly through solar energy as a clean, renewable energy, is the development of new energy in the world. Inspiron 510m battery Inspiron 600m battery

 

The EU Joint Research Center study shows that in the future global energy mix of renewable energy, particularly solar energy photovoltaic power generation represent a growing share of solar energy by 2030 will represent 10% of the global energy mix by 2050, this proportion will increase to 25% in 2100 to reach 64%.

 

On the other hand, governments attach great importance to PV industry and to address the global financial crisis to cultivate new economic growth point of the milestone. Among them, the resumption of Japan’s policy of solar power, Prime Minister Taro Aso has announced that in 2020 the size of the solar power generation in Japan is 20 times higher than the current expansion. Obama’s New Energy the U.S. government will strengthen the U.S. economy as the main point of departure, plans to invest 150 billion dollars over the next ten years to fund research into new energy. The Australian government announced in May 2009, to spend 1.05 billion U.S. dollars to build the biggest factory in the world of solar energy, said the project’s future could be powered 1000MWp. In 2020, the Australian renewable energy supply of power will reach 20% of the total electricity supply.

 

Currently, China is the world’s largest producer of solar cells, PV has 11 overseas company listed in 2008, production of photovoltaic cells tablets 1.78GW, ranking first in the world, representing 26% of world production. A1175 MacBook Pro 15 inch battery

 

However, with the largest manufacturer of solar cells in contrast, in 2008, the photovoltaic solar capacity in China is only 34 mW, the total installed capacity in the world of only 0.57% of the total national installed capacity of 140MW of calendar year, are not sufficient, Spain 2008 annual installed capacity of 2511MW of 5.58%. In addition, the production and the huge gap between demand, combined with a lack of core technologies, the industry, but also led to the photovoltaic solar industry, dependence on outside of China is too high.

 

In this context, to make the domestic PV market to achieve a major development, from the enterprise level, should accelerate product development, improve the conversion efficiency of solar photovoltaic products, reduce product costs. Satellite M105 battery Satellite M40 battery

 

From the perspective of government, at present, the solar photovoltaic industry in the development efforts of the policy of our country and the implementation of the scope of subsidies, has been further improved, including subsidies electricity prices, tax breaks, demonstration projects in areas such as politics has been strengthened. In March this year, the Ministry of Finance, Housing and Urban-Rural Construction jointly issued the “Solar architectural applications interim measures for the management of Fund financial assistance, through financial assistance to implement applications for construction Optical support demonstration projects to address the building integration of solar photovoltaic design and construction capabilities of the poor implementation of technical standards related to the lack of realization of components and building the capacity of solar PV module production low and so on, in order to initiate the field of solar photovoltaic applications in rural markets and urban construction, and lead the development of solar photovoltaic industry.
