Good work guys... current batteries suck.
If Apple could get an exclusive deal on these like they did with the iPod hard drives, then..

I submitted this 6 hours ago, but don't see my credit anywhere ... (I know, quit whining! But I've never figured out how submissions work here.)
hob might think this is not prime MacRumors material, but I submitted it for posting here after spotting it because it has a HUGE impact on how we use portable devices.
An iPod with a 60 second recharge time is pretty radical.
And Apple should be near the top of the pack to get this technology from Toshiba - don't forget the iPod mini hard drive connection.

Analog kid said that it would put out something like 103W, so someone figure it out...But to put it in perspective, an oven uses a LOT of electricity, as does a hairdryer or clothes dryer. Luckily, Coal-powered electricity is cheap for the momentDrNeroCF said:
How does a battery charge this fast? Can anyone explain how this could be achieved? I mean this is not just a small improvement. This is a major leap. It is completely mind boggling.
Sure is impressive, I heard about this earlier, they are saying it will be used in electric cars. Obviously that would be a huge thing for an electric car because it would lift the traveling barrier. You could drive for say 50-100 miles, and then stop for 5 min to charge up at a rest stop. I'm not sure what the current range on electric cars though.

Well technically the only reason a battery doesn't discharge almost instantaneously is because the battery has internal resistance, so when you short it it takes time. A battery is essentially just a capacitor which is just two metal plates separated by a distance. When you place a voltage difference across it current doesn't actually flow, but it acts just like it is until so many electrons gather on one of the plates that it is essentially full up. This usually happens really fast if there is not much resistance. So what toshiba did was make some sort of lithium lattice that is extremely easy to "fill up" with extra electrons. I would predict that if the battery is that quick to charge, then it is probably extremely low Thevinin resistance, and would probably discharge very quickly if shorted.
And about blowing your fuses, I'll explain that later in detail if you want, but the battery won't draw enough current to blow any fuses.
This sounds like a great breakthrough, but it doesn't solve the biggest problem with batteries: charge capacity vs. size+weight. Once we have laptop batteries that can run 2x or 3x longer than the current ones can, at the same size and weight, I'll be very happy. Add in this Toshiba technology to that and you finally have viable battery technology with few compromises. It'll happen eventually, and probably long before/if hydrogen fuel cells are available for portable applications. This Panasonic battery technology looks promising, though it's for alkalines, hopefully similar advances will be developed for laptop use.

Maybe a faster charging iPod battery will silence the whiners demanding longer battery life overall. For me, I find waiting for my current iPod to charge more irritating that the length of the battery life itself. This will be a great technology once it trickles down.
from what i learned in my limited electronics class (high school, so I'm probably wrong) the reason why batteries take so long to charge or discharge is that the chemical reaction necessary to produce a Voltage has it's physical limitations (i.e. chemical reactions require a certain amount of time to complete). It looks like Toshiba is using some form of nano-technology to speed up the chemical reaction and efficiency in the electrolyte so that it quickly refills it's Lithium ions (the process of creating a negative charge so that there is an electro magnetic force differential i.e create voltage again).
this quote is the only piece of info I found that kinda goes into it.
"A breakthrough technology applied to the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store vast amount of lithium ions, without causing any deterioration in the electrode."
I am excitied about this technology. Hopefully it actually comes to fruition.

I am quite amazed at this new battery-it's radical, as it shortens recharge times-could be used in iPods and Powerbooks, revo. Apple might just be interested in this for any future iPod's or Powerbook in next few years.
Wow... if this technology is safe then I can see public charging points for things like mobile phones, iPods etc. taking off... I suppose I would pay £1 to charge my iPod to 80% in a minute while I was waiting for the bus/train.
One minute... it just sounds unbelievable. I have a battery charger that fast charges batteries in 15 minutes, I thought that was fast!

Hybrid cars never need to plug in. The way this technology could improve hybrid cars is by making regenerative braking and charging by the generator / alternator connected to the fuel-burning engine much more efficient. This in turn could increase effective horsepower, making for better acceleration.d.perel said:As a side note, this would probably be great for a new gen of plug-in hybrid cars.
I dont care about ipods but im thinking cars
Think about it. you have a full hybrid car. the engine runs for 5 minutes to full charge batteries . the batteries power the electric motors to run the car. if all the engine does is recharge the batteries every 2 hours.. well just imagine the fuel economy,
600mpg?
its possible

You couldn't charge a modern laptop on a 120V 15A circuit in a minute with this technology. Maybe 6 minutes without tripping a circuit breaker. Or install a new 50A 220V circuit just for battery charging.
I'm having trouble believing these claims - it's astonishing. Is there a Nobel Prize in Materials Science?
