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.
