According to Recurrent's recent report, most EVs lose only about 10% of SOH (or battery capacity/range) after 100,000 miles.
>> LFP batteries generally have about 3x the longevity of other lithium ion types <<
This is not true at all. All LFPs in EVs degrade much faster than other lithium ion batteries:

The brand new LFP batteries will degrade substantially quicker. There's not long-term retention data for LFP batteries on the market yet, but the trend tends to be substantially faster degradation. Trends show them stabilizing around that 10% degradation mark in about half the time as non-LFP batteries - around 50,000 miles instead of 100,000 miles."
Even in ideal environment, such as ESS, LFPs would degrade substantially faster under high SOC/high c-rates (eg, EV).
- elihu 3y agoLFPs lose some of their capacity early on, but then the degradation is much slower. It's just a weird quirk, it doesn't mean they're going to fail quickly.

We don't know anything about LFP's longevity in EV profil, and, while there is no long-term data on LFP's true lifespan in EVs, it's been demonstrated that LFP could lose as much as 1/3 of its lifespan under 100% SOC in ESS profile. LFP's are already mostly limited to entry-level, low-range EVs due to its other technical short-coming in moving vehicles (ie, low energy density and weight). This quick degradation makes LFP even less appealing in vehicles.
