Japanese research and development firm Eamex claims to have found a new way to increase the typical average life of a high-capacity lithium-ion battery. Eamex's new technology will allow the demanding batteries to sustain over 10,000 recharges over the course of 20 years.
I remember just a few years ago how thrilled we consumers were with 1200-1400mAH in NiMH AA cells. Now we have twice that capacity ... It's very exciting seeing both consumer and commercial-grade battery technology mature.

Thank you for posting this Clint -- I'd heard of this from a friend but he could not give me the link, but now I have it.
I am happy to hear of this, but I take it with some skepticism, in that this is a projected life time, not a real one. While I would *love* for this to be true, I wonder what un-thought of chemical reactions there might be, affecting the battery some years down the road.
To give an example that fuels my skeptic tank, consider recent disk drives and the enormous published mean time between failures for them. They were garbage, and looking at WD disks (scorpio blue), they don't publish MTBF any more.
So while I want aa batteries with 13.1AH capacity and 12,000 recharge cycles, I'm going to have to wait for them....... ;-)
