I agree that the 40-kWh LEAF looks like a very limited-run product. AESC (now owned by LG Chem) makes that battery and I wonder if this chemistry will be around once the 60-kWh version comes out.
Based on the degradation rates we have seen with the 30-kWh LEAF batteries, I won't be surprised if the 40-kWh chemistry is even worse. The 60-kWh version uses 811 NCM from LG Chem, which, in principle, is less tolerant of high temperatures than the 622 used in the 40-kWh version. So it may be true that 811 MUST have TMS in order to have any reasonable battery life.
I'm also wondering if Nissan going with a turnkey electric drive from LG Chem including battery, charger, inverter and DC-DC converter like GM did with the Bolt or are the upgraded electronics in the 2019 LEAF coming from Nissan.
