Toshiba LTO SCiB

Post by Richo »

Well finally some of the Toshiba's SCiB Lithium Titanate batteries are hitting the open market.
Here is the link to Toshiba's spec on the cell.
http://www.scib.jp/en/product/cell.htm
The ones that seem available are the high power 2.9Ah 2.4V cells.
They claim testing at 10C charge and 10C discharge continuous with over 40,000 cycles.
A peak current of 200A puts this in at 65C :o

As a handy feature it has screw terminals and standardised bus bars.
So no messing about with manky pouch cell tabs! :P

They seem to be priced around the $12 mark in one-off's.
So this is about Double the price of headways/Wh
But given the higher fill factor with the SCiB and higher peak currents could be worth it in some applications.
So the short answer is NO but the long answer is YES.

Been following these for a while now - great to see they've hit the market.
Interesting cell architecture too - looks an awful lot like the cells used in the BMW i8

Claimed peak power is 420W which means peak power is at 60C.
So a 2kWh($3,500/44kg) pack would have 120kW peak.
And with normal use 40,000 cycles...

:idea: All they have to do now is make the internal battery structure last 100 years.(shelf life)

Nice vid.
I like how they use a blow torch on the batteries at every chance. :twisted:
And stick the batteries together with double sided tape.
Even the robot picks the batteries out of the box slowly. :lol:
So the short answer is NO but the long answer is YES.

Agreed.

I thought that was plasma for roughening the surface, so the adhesive sticks better. But I didn't look closely.

You're probably right - I've never seen anything exactly like that.

The start of the vid shows samsung as the battery supplier so they wont be Toshiba or possible even LTO's.
They look similar tho.
So the short answer is NO but the long answer is YES.

Just read that BMW uses Samsung SDI to make their prismatic cells for the i3.
