"We have found a way to extend a new lithium-ion battery's charge life by 10 times," said Harold H. Kung, lead author of the paper.

Just another step on the road to better batteries. It will be interesting to see what batteries will be like in 10-15 years.

LG Chem uses silicon at the anode.

They also "drilled" 10- to 20-nm holes in the sheets to speed up the recharging process, by as much as ten times.

Ugh, I'm worried about this. I can't access the paper to see how they did this, but if they did it using something like lithography, this might be way too expensive to do in practice. The features on a computer's memory stick are about the 10-20nm size, and they're not exactly cheap!

[edit]
I just found this from the press release:

Kung’s team also used a chemical oxidation process to create miniscule holes (10 to 20 nanometers) in the graphene sheets...

So that might end up being okay in terms of price.
