Always good to hear about new batteries but these should be in use in laptops right away not later.

I agree – it will be exciting to finally see some real advancements in battery technology. That kind of charge retention after 2,000 charge/discharge cycles is really crazy. I can only imagine the prices, plus, will this mean people will buy less batteries? lol

Nothing to see here. Sony is doing nothing more than ripping off A123 Systems and their nano phosphate cells. And 1.1Ah in an 18650?! This will do no good for laptops, not for a longer running one, at least. These are totally about high current drain devices.

It's probably too expensive to use in normal consumer electronics products. Notice how Sony avoids talking about price.

I hope this will be a revolution in lapdop batteries..

Best Regards.

Well, isn't that where A123 was several years ago with their 18650 cells?
I recharge these to 100% in 15 min, and I'm not even pushing.

Correct (well, not the ripping off part; there are numerous people doing Phosphate long before A123). Not only is it 1.1Ah, but it's got a nominal voltage of 3.2V vs. normal Li-Ion of 3.6V. Thus, this has LESS THAN HALF the runtime of a standard laptop cell. Actually, probably under 40% of the runtime. So when your regular “crappy” laptop batteries has only 50% of its original runtime, it still lasts longer than one of these brand spanking new.

Again, it's about power tools, not laptops

no revolution here. Lithium-Polymer batteries have better energy density, up to 200Wh/kg, see:
http://en.wikipedia.org/wiki/Lithium_polymer

The ones used in model aircraft have about 150Wh/kg, have a continuous discharge current of also 20A, and a continues charge current of 10A, which allows them to charge almost fully in 12 minutes. These cells are also used in the new macbook pros, and some IBMs. (and yeah, they are the ones that explode )

Phosphate, yes, but not nano-phosphate. That's the key difference with A123's LiFeP04 cells, and their ability to be rapid charged and discharged. Everything else though, you're correct.

Hey, get back over to RCG!

I have A123 26650 cells for my electric scooter. They can provide 70 amps of continuous current at 3.3V.

70 Amps… . 70!

I almost melted my multimeter testing them! at 3.3V!!!

where can I buy these

These are some impressive stats, and I forsee Sony holding a large market share if advancements such as these new cells continue.

These would be interesting batteries – used for a boost mode on my EV, with some means to charge them from my Lead-Acid Batteries, but use them in parallel for hard acceleration! I would only need maybe 10 – 15 Ah Capacity – since they can deliver about 20 Amps per Cell (about 18C) so 15 Ah Capacity should be able to put ot about 300 Amps for a couple minutes – more than enough to jump back into traffic on a freeway pull off moment!
