I agree Nissan may have had the more heat tolerant chemistry in their long range plans much earlier than summer 2012 when rapid capacity loss in Phoenix quickly became a severe problem for the LEAF.
I am less confident that the lizard battery is "truly developed, vetted and tested already".
The real testing has just begun.
Nissan appears to have done about the same accelerated aging on the new battery that they probably did on the 2011 battery.
That didn't work too well the first time.
We will only know how well it has worked this time in 1 1/2 to 2 years.
Might have more confidence in the lizard battery if Nissan had overall coulombic efficiency testing done of the 2011, 2013, and 2015 batteries by Professor Jeff Dahn (Dalhousie University) but I'm not sure they did that.
