Electrovaya introduces new long-life 40 Ah Li-ion cell
14 October 2015
Electrovaya Inc. and its wholly owned subsidiary, Litarion GmbH, introduced a new 40Ah lithium ion cell (“Litacell LC-40”) promising extraordinary cycle and calendar life (nearly 9000 cycles at 1C/1C and 100% DoD) and safety properties due to the unparalleled stability of Separion flexible ceramic separator membrane. The 40Ah Litacell contains optimized NMC/graphite based electrode chemistry.
Lithium Ion Cells have cost and safety challenges and the Litacell LC40 provide the breakthrough technology with capability to drive down holistic costs by an amazing 50% while providing unparalleled safety Nearly 20,000 electric cars from a leading German OEM are on the road today with Zero Safety incidents, a rare feat in electric vehicles, a compliment to our unique ceramic embedded separator, Separion and our world class electrodes which now drives the Litacell technology.
—Dr. Andre Mecklenburg, Chief Operating Officer of Litarion
Litacell 40Ah cells are now available to customers in Europe, North America and elsewhere.
Electrovaya, through its fully owned subsidiary, Litarion GmbH has manufacturing capacity of about 500 MWh/annum.
So that is 1 / 70th of Tesla's manufacturing capacity of one of its forthcoming plants.

Clearly not very good energy density or specific energy. I went to their website to find the specs and only got the following "wording" but no ACTUAL NUMBERS LMAO!!!:
"Energy density is widely considered the most important metric of a battery technology. It determines the size and weight of the battery system. Higher energy density translates into smaller, lighter battery systems or applications with longer run-times or ranges.
Electrovaya's technology is primarily characterized by superior energy density. Its nanostructured Lithium Ion SuperPolymer® 2.0 platform technology provides a faster, more efficient transport of lithium. This equates to its ability to pack more energy into smaller and lighter spaces. "
So...you guys got nothing. If you did, you'd be trumpeting the numbers to anyone that would listen.

They state the energy density and performance have improved with the combined technology. http://www.knowledgefoundation.com/lithium-battery-power/commercialization/ Pretty impressive if you ask me. Just in case the links don't work the specs are 490wh/L and 213 wh/kg.

Seems to compare with Panasonic-Tesla units with energy density but with extended live duration? Probably more expensive, if it last 3x to 3x longer?
Could be ideal for e-taxis, e-buses and other heavily used e-units.

@JohnH, thanks for the links!
Those specs look pretty good, but NOT great. They're a good bit behind the Panasonic cells that Tesla uses today HOWEVER, the 9,000 cycles is spectacular.
It's also possible the new cells have better energy density than that as it looks like those numbers may be from their older cells??? Hard to tell if the new Litacell LC-40 is the same as what's on that page or something new.
I will say that with the 9,000 cycles, I'd expect them to have outstanding POWER density as the cycle life and power density usually go hand in hand.
They really should release actual specs of these cells instead of playing coy.

9000 cycles at C/1 is Powerwall territory.
