Stanford's nanowire battery leapfrogs Li-ion

 

Stanford claims its latest advances in silicon nanowires have it building batteries with 10 times the capacity of existing Li-ion cells. Apparently people have been trying to stuff silicon -- which has a much higher capacity than existing materials -- into a battery for decades, but since it swells when charged with positively charged lithium and shrinks during use, the silicon has a tendency to "pulverize." Who knew batteries could be so dramatic? Oh, right. The advancement at Stanford, led by Yi Cui, builds the battery in the form of silicon nanowires, giving the silicon room to grow and shrink without damage. A patent is being filed, and Yi Cui is already considering forming a company or licensing the tech to a manufacturer.

 

   

UCLA nanowire discovery could lead to faster, stronger, smaller electronics

  

Advancements in silicon-germanium have been going on for years now, but a team at UCLA is convinced that their discovery really is "the next big thing." For scores now, microchip makers have struggled with miniaturizing transistors as the public at large demands that things get smaller and smaller. Thanks to researchers at the aforesaid university, it's looking like silicon-germanium nanowires could be the key to making the process a whole lot easier. According to study co-author Suneel Kodambaka, the new nanowires could "help speed the development of smaller, faster and more powerful electronics," also noting that they're so small that they can be "placed in virtually anything." Which is great, because the Adamo XPS is just entirely too pudgy.
