These men mean business. Usually this kind of news states "be available in 5-10 years".

It would be pretty sweet if the 2015 Model S had a 1000 mile range!
3x the capacity would be amazing, for ALL things portable, but it would give a huge boost to the electrification of our automobiles.

oh man the first company that uses this tech will look very good vs the others. Just like Apple did when they first boasted longest battery life on their laptops. (And MacBook Pro still have one of the longest)

Will they be cheaper? almost always if some thing is better the cost goes up despite it being cheaper to make. I hope they get the cost of research back from licensing and the public can benefit from advances in technology. Just give it a trade name.

If only I had a $ for everytime I read about some technology like this. Let's see where this tech is 12 and 24 months from now.
Derek - manufacturers aim to give cars about 300 miles in range. It would be much better to rather install a battery 1/3 the size (and hopefully in weight) of the current Tesla battery with the same range and hopefully or most likely pay LESS for the car (since the battery is about the biggest cost component of the car). The battery could actually be a bit smaller than 1/3 the size and still achieve the same mileage as the original battery because of the weight savings when lopping of 2/3's of the battery.

This triples the capacity, not necessarily the range. This spells great news as far as cheaper batteries down the road and if cathode and electrolytes are also improved, could mean 3 times the range. This is great news.

Today we have the Tin Whisker, that could expand Li-Ion capabilities 3 times. Days ago we heard abt IBM working on the Li-Io-Air to duplicate current efficiencies, Tmrw we will see another fancy lab-idea in the same tune but with a different approach.
Where is the "TEC-MIXER", If 1+1 is 2, then we should have someone to make sense and built something that works better putting all the pieces together. I want to see the Tec-Mixer. Max

Can't wait to put these in my RC planes!

If anyone were to look this up you would find tin anodes for lithium ion batteries is not a new idea. Several Japanese companies worked on this about a decade ago. I will be surprised if you can buy a Lithium ion battery with a tin anode in the next 2 years, most likely you won't see it in the next decade if ever but we can always hope. The author would do all the readers a favor by pointing out the problems of of using tin, but maybe it is better not to have reality intrude on our dreams. There is always a better battery just down the road just like there is always a better engines down the road, and so there is but they are invariably just a little better. When are we going to see those silicon anodes they have been talking about for the last decade and their large capacity improvement?

Would a conductive aerogel (e.g. carbon aerogel) work better?
