EXCERPT: “Rather than discarding this forgotten batch, they decided to test it by building batteries using these particles. It turns out they have potentially solved the problem of using aluminum for the anodes in the battery. The extra long soak meant the anodes did not expand and contract, in fact they created a battery that over 500 charge/discharge cycles retained up to four-times the capacity of the equivalent graphite anode batteries. These batteries last considerably longer in terms of usable lifespan and, according to MIT, can hold up to three-times the energy.”
There we go again, it is a three months cycle. For the last 6 years every announced breakthrough of more than 10% at a time was soon never heard of again.
Nuts, what model Opus will charge these??? Never mind, my Nitecore D4 has a switch for that, only 150ma, but it will do it!!! LOL
I had high hopes for lithium-titanate from AltairNano back in 2007… they tanked and the batteries are not being developed for small scale applications…
Actually, if ANY new magic-battery-foo comes to fruition, I would bet Bort’s left nut that it is this one. The processes for making it is simple, well defined, scalable, and practical. That said, I’ll hang onto Bort’s right nut for a while…
Did you guys catch this part? I clicked through from the article brad linked, back to the larger article, where they claim that the aluminum is able to hold a higher energy density than the graphite they’ve been using. So, it sounds legit. Imagine a 18650 cell with 10Ah capacity as well as a lifetime of re-charge cycles! Electric vehicles are sure to see the biggest benefit from this, followed closely by laptops and cell phones. In cars, I’d expect to see the same size or not-too-much-smaller batteries with much improved run time. In laptops and cell phones, I’d expect something in the middle - somewhat smaller package and somewhat longer run-time.
I would hope that with the greater capacity comes greater output current, but they didn’t mention that in the article, or at least I missed it if they did. It would be cool to have a 4Ah 14500 with 15A continuous current rating, or something like that. You guys will be glad you bought a 100% copper K6 from Krono’s group buy.
you are usually the most skeptical one, however the vast fortune i have attained from all the bets on the failed breakthroughs is more then adequate to fill an envelope full of cash for your personal enjoyment (or to return the favour)
