Silicon Nanotubes for High Efficient Lithium-ion Batteries

Posted on Thursday, September 24, 2009 posted by posted by Mak @ 12:33 AM

Researchers from Stanford University and Hanyang University in Ansan, Korea, in collaboration with LG Chem (makers of the Chevy Volt battery), have made a breakthrough that could change the future of electric cars. They have shown that by replacing the conventional graphite electrodes in lithium-ion batteries with silicon nanotube electrodes (silicon nanotubes, not the more common carbon nanotubes), 10 times more charge could be stored. This could not only greatly extend the range of electric cars, but it would also make gasoline-electric hybrids more efficient by allowing them to run in electric mode for longer periods.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
