Guys,
Was this in one of the energy rags I get. It is the future of battery technology.
"Toshiba International Corp. has established U.S.-based sales and technical support for its new product, the Super Charge Ion Battery, (SCiB). Toshiba says this lithium-based technology reaches 90% of its charge in less than five minutes and features a life span exceeding 10 years."
Best, Dennis

The problem with all these announcements is they are always in the future tense and so they may last for 10 years, but when will they be available? VD~

Guys,
Here is is the web site - I think they are available now. They look like something similar to A123's seem to have better charging rate but still limited on size 4200mah.

Hey Dennis,
The listed discharge rate for these batteries is only 8 amps. I'm not sure that is well suited for our use.

4000 mah weighs 2.2 pounds!

Hey if the 4 stroke guys say that weight doesn't matter..... S?P

If you click the "Brochures" tab on that page, you see some fairly impressive performance and safety claims. Discharge rates up to 50C, Discharge depth of at least 50% better than LiPo's, no short circuit due to mechanical damage, High Charge and Discharge capability. Right now their 4.2 A-hour cell is about twice the weight of an A123 2.3 A-h cell, so energy density is roughly the same as current A123 technology - which is still somewhat inferior to LiPos - however, their 6000 cycle claims for cycle life will far outstrip any current LiPo - sounds like they might possibly have a future. I didn't try to find any data on cost but acceptance and general usage will lower the cost just as it did with LiPo's.

I guess my question is "Are they actually available?"
-
They have set up a US distribution office - I've got an email in to see if any more info is available yet regarding availability and price structure. I'll update this thread if I get anything back.

Here is the answer I received to my inquiry about these cells --

Mike,
We are currently selling only as custom packs rather than as cell. What is the voltage and capacity of your application? What is the application?

Subject: SCiB cells
I am interested in more information regarding the SCiB cells –
In particular, I am interested in the loose cells as opposed to the assembled batteries –
Are they currently available?
What is the (approximate) price for, say, quantities of 1, 10, 100?
Are you offering an “evaluation kit” of some kind?
I have both an interest as a power source for a product that is currently in design stages here at my work – Etrema Products in Ames, Iowa – and as a hobby user of rechargeable cells in model aircraft.
Thank you for any info you can supply.
