In January this year, the news broke that an assistant Professor and his team at Stanford University had invented a revolutionary battery technology capable of holding ten times the energy of existing Lithium Ion batteries. Now the Professor's ongoing research is being funded to the tune of $10 million by a startup university in Saudi Arabia and conspiracy theories are flowing as thickly as oil.
Assistant Professor of Materials Science and
Engineering, Yi Cui, has succeeded in developing a novel type of
Lithium Ion battery that has an order of magnitude greater energy
storage using silicon nanowires at the anode. The amount of lithium
stored in a forest of tiny silicon nanowires, each with a diameter
one-thousandth the thickness of a sheet of paper, is much greater than
can be stored by the carbon in current Lithium Ion batteries.
Lithium Ion batteries, widely used in mobile phones, cameras and laptop
computers have been touted as the most promising near term storage
technology for electric cars and a potential replacement for petroleum
based transport. However, the storage capability of the current
generation of batteries still falls well short of gasoline. Silicon
nanowire batteries could be the tipping point that makes long range
electric cars a reality.
When announcing the breakthrough technology in January, Professor CUi described it as a revolutionary development.
"Given the mature infrastructure behind silicon, this new technology can be pushed to real life quickly," Cui said at the time.
Cui, a native of China's Guangxi province, also said that a patent
application has been filed and that he was considering formation of a
company or an agreement with a battery maker.
However, a new
announcement out of Stanford has put a
new slant on Professor Cui's research effort. Professor Cui has
accepted a whopping $10 million grant from recently formed King Abulla
University of Science and Technology (KAUST) to continue his research.
