90% recharged batteries in less than 5 minutes that will still recharge even 10 years later? Where do I sign up?

When many think of rechargeable batteries the first thing to mind when making a wish list is a longer life for the battery, but that is only part of the issue with rechargeable battery. Another big part of the picture when it comes to rechargeable batteries is how long it takes to charge the battery.

Toshiba announced today that it has developed a new type of rechargeable battery dubbed the Super Charge ion Battery (SCiB). Toshiba claims the new battery will mainly target the industrial market, though representatives hint the technology may eventually find a home in electric vehicles.

The main claim to fame for the SCiB battery is that it can recharge to 90% of total capacity in fewer than five minutes. Toshiba also claims the battery has a life span of over 10-years.

Toshiba says that it adopted a new negative electrode material, new separators, a new electrolyte and new manufacturing technology to bring the SCiB to life.

The SCiB batteries can recharge with as much as 50 amperes of current and but with capacity loss after 3,000 cycles of less than 10%. Toshiba also says the battery has excellent safety with the new negative electrode material having a high level of thermal stability and a high flash point. The battery is also said to be structurally resistant to internal short-circuiting and thermal runaway.

Anyone familiar with the technology industry will know what Toshiba is most known for, the massive battery recalls in notebook computers from early this year.


Though not as widespread as Sony's battery woes, Toshiba wants to put these fears of using its products out of the minds of buyers. If the battery technology makes it into notebook computers and other consumer electronics, it could revolutionize mobility.

The first of these batteries will be ready for industrial uses in March of 2008.

Too bad they don't say how many cycles the battery can go through before it's all used up. 3000 cycles for an electric vehicle can be used in less than a year. I guess that would depend on how far the car can go in 1 charge, among other things.

It's all about wear leveling and managment. The NiMH cells are typically advertised to lsat around 500-100 "Full discharge cycles" but we see some of them still going strong in some Priuses at 250,000+ miles. Li-Ion technology were typically advertised to be around 300-500 cycles and we're going to put them into EV's.

I think 3000 cycles is far greater than anything in the consumer market right now....assuming they actually do what it says it does.

Oh, from the PR itself

quote:
2. Long-life cycle
Capacity loss after 3,000 cycles of rapid charge and discharge is less than 10%. SCiB has an excellent long lifecycle, and is able to repeat the charge-discharge cycle over 5,000 times. This means that the SCiB can be continuously used for more than 10 years with a once-a-day recharge-discharge cycle.

I won't be buying an electric car if I have to recharge it 8 to 10 times a day...

5 minutes would make it essentially the same as filling up your car at a gas station. So it makes it feasible to take your electric only car on cross country trips. You might have to fill up more often, but at least it won't take you hours to recharge your car battery pack.

That'll be good for resteraunts.

Imagine; 2-3 parking spaces at every fast food and Cracker Barrel across America along high-ways with a simple plug in port and a device like a coin-operated parking meter.. feed it a dollar, or whatever the energy is worth plus a profitable mark-up, then go to the bathroom, get a cheeseburger, or sit down to eat. Come back, ready to go.

Beautiful. Probably not a huge profit machine, but a boon in convenience.

That would actually be a brilliant idea. Kind of like having Redbox at all of the McDonalds restaurants. It is just power coming off the grid. All they would need is some electrical work and they can start generating a revenue stream. It is 5 years off at the very earliest, but it is good to get the marketing in front of the problem for once.

But perhaps a hybrid vehicle where the batteries are being recharged by a gasoline engine and recycled energy from the braking system? Granted though, even then I doubt you'd see 8-10 full charge/discharge cycles.

If this battery can put in anywhere near as much mileage as my car can put on a single tank of gas (somewhere in the region of 500-600km depending on conditions and aggressiveness), then it'll be charged/discharged nowhere near 3,000 times in a year. It just makes sense not to plug it in when it's not needed. Do you fill your car up with gas after every trip? The same would apply here: only plug it in when it's needed.

As for mobile applications, what would be really great is if they could make it backwards-compatible for older applications. When my laptop battery eventually dies, I'd love to buy one of these to replace it instead of using "old" Lithium ions. And cellphone batteries could last even longer and charge in even shorter amounts of time. My Samsung's battery only takes about an hour to fully charge from being completely dead and if I don't make any calls it lasts me about four or five days without needing to be charged.

It would be nice, however, even if it works the recharge benefit wouldn't be there as you'd have to replace the recharging circuit in the notebook computer as well. Still a step up though. Same with the cell phone.

They could provide an external charger for retrofit applications. Then you could either let it charge slowly in place, or pull it out for a quick charge.

OTOH, it does beg one more question. Anything that is sucking up 50 amps of current is likely to get warm, and if future units are built into consumer electrics you're talking about providing much more robust power supplies and power routing.

to make it compatible with existing laptops (as ina replacement battery) the charging circuit would need to be able of handling the high current draw, which isn't likely.
Also, if they're stating 50 amps of house current (120v), anybody happen to know how many 50 amp breakers you have in your house? damn few...

I don't think I've ever even seen a 50A 120v circuit. Most anything over 20A is 208/240v

They aren't claiming 50A of household AC current, it's the current rate for charging the cells at their respective voltage.

Note that means in some applications the voltage could even be higher than 120V, but for most it would be lower.

Note also it is meant for industrial uses, not a replacement for your consumer devices that're charged from a residential wall outlet.

IF the tech took off and everyone started buying battery powered cars, it wouldn't be a big deal to wire a garage to supply 50A @ 120V, but more significant would be the toll on existing power infrastructure because it means up to multiple times the power delivery to any part of a grid in the evening when everyone comes home and charges their car.
