Superpowered Li-ion batteries coming

Silicon nanotubes. [Link]
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."
They are talking about commercializing it.

Lack of powerful batteries has been holding us back. Almost all other power generation technologies has advanced (I'm looking at you, Fusion), but not batteries. Maybe it's time for that to change?
