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.

Ok power output figure is here.

2.4v * 4.2amp / .15kg = 67.2 Wh /kg

Power needed for average vehicle to cruise at 100kmh = 7.5kw

7500w / 67.2Wh = 111.6kg is needed to travel at 100kmh for an hour.

you'd probably want 500km range so...

111.6kg x 5 = 558kg

Is this correct?

Anyway in comparison Tesla Roadster has following spec

# Full-charge time: 3½ hours.[12]
# Electric energy: about 53 kWh
# Total mass: between 900 and 1000 lbs (400-450kg)

That's battery only

You are a little off. A really efficient EV car can get 4 miles down the road when consuming 1 kw(hour is assumed).

Lots of things can impact how much 'power' is required for highway speeds. Rate of discharge and voltage of the batteries in addition to any gearing and the torque available in the motor.

Also, the Tesla Roadster uses Li-ion batteries (which hold 3x the power kg for kg as Toshiba's new battery technology). Tesla's battery pack weighs 1000 pounds and has a range a little over 200 miles in a very efficient design. Using these would require at best 3000 pounds, and since you want a 500km range I would push that up to two metric tonnes. Not going to happen.
