Lithium-Ion Battery Life Could Reach 20 Years

It's about the total lifetime of the battery, not a single charge.

That might be interesting for use in cars, but it has nothing to do with the "super fast charging and longer-lasting batteries that will liberate using of mobile devices" that the article starts with.

Also, the article says nothing about the energy capacity of the battery. It merely states

  Eamex says it will ship a battery with about 10,000W of power per kilogram

yeah... for how long?

Power and energy are frequently confused. Power is the rate at which energy is generated and consumed. To answer your question the battery rating should preferably be given in Amp-hours or kWh. I suspect the author wanted to highlight the energy density of the battery, connected to a charger the battery should be able to provide 10kW continually for its life. 10kw/kg is actually impressive.

> [...] should preferably be given in Amp-hours or kWh [..]

How about Joule?

I don't trust websites that look like that one without extra research (no offense), and google didn't give me too much promising support for the claim. Where is my laptop battery revolution? I want a longer lasting battery =/

"What Eamex has done is figure out a way to stabilize the electrodes and prevent the deterioration of tin. Why's this important? Because it means the batteries can withstand a lot more charge and discharge cycles. We're talking about over 10,000 cycles with a shelf life of 20 years."

Not quite what the headline made it sound like...

(WTF that site prevents copy so I had to rewrite this by hand. LAME. Maybe it's time for me to try NoScript after all.)

It is a very bad way to try and stop someone from copying. A better way used by quite a few media is to use javascript and copy a backlink at the same time (very good for blogging and the media at least gets some link juice).

You are right the headline is a bit sensational.

Fast-charging is already here for Electric Cars. AeroVironment charging system with EnerDel battery. This system is targeting the Think City cars that are going to begin production in the U.S. later this year.

I've seen these claims about dramatically extending the number of charge cycles in Li-Ion before. Never seen a product yet get to market. I don't believe this claim either. Show me an actual product and prove me wrong.

Have to agree with jeroen's comment but the battery thing is certainly a hot topic. A paradigm changing topic depending on advancements.

seem like a new 'sink technology task' for Energy Lobby
