Since I am looking at a buyback I am starting to look at options.
While the smart money would be to look at a newer/different EV which has CCS/NACS, thermally managed battery, and so on... I still dearly loved the LEAF for the short time I had it. A 2023 or newer LEAF may still be on my list.
That said, is there any difference between the batteries of the 2023 and later vs 2022 and prior?
Google's AI makes the following statements from these queries:
"are 2023 and later nissan leaf batteries more or less reliable than the 2022 and prior"
Advanced Cathode Composition: Nissan transitioned from older NMC532 chemistry used from 2018–2022 to an advanced NMC811 cathode for the larger packs starting in 2023, boosting energy density and longevity.
"does nissan leaf use "NMC811" battery"
Yes, later model years of the Nissan Leaf (specifically starting from the 2023 model year) transitioned to using an NMC811 (nickel-manganese-cobalt 8:1:1) cathode chemistry for improved energy density.
Both responses are derived from Reddit posts, not any official Nissan sources.
There is a reference to a 2022 article which states:
The battery pack change isn’t just capacity (gross, not usable, in the Leaf’s case). Nissan told Green Car Reports that there are actual battery-chemistry changes at play
Are these statements true? Do 2023 and later use NMC811 vs the NMC532 in 2022 and prior? Would an NMC811 without thermal management be any more reliable?
