SCIB in US 2012 i-miev?

Not really. Not yet.

We still have older-style Yuasa batteries. Here is what i found on a Japanese web-site:

Most noteable characteristic of SCiB is lifespan. The number of cycles for a SCiB, according to Toshiba is 4000 as opposed to a thousand for Yuasa LEV50.
Here is a comparison of GS Yuasa vs Toshiba:

85% capacity is retained at charge cycles at 25 degrees centigrade (~70F). SCIB data was taken from a 4.2AH cell from EV-neo Honda bike. Capacity retention is 90% after 6000 cycles with the same temperature.
For a 1000 cycles, Lev capacity is 85%, whereas SCIB is 98%.

I'll do some math to project the retained capacity over time...
