It certainly can vary quite a bit as the graphs in the article show. Seems that cell chemistry, thermal management, and total cycles are the largest drivers of degradation. EV’s with generally smaller, more frequently cycled packs, no active thermal management, and cell chemistry not optimized for that use case will not fare well in hot climates. Something with a larger liquid cooled pack, that doesn’t experience as many cycles, will fare much better regardless of the chemistry and easily still have useful amounts of capacity after 20 years.

As a data point, this is from an early 2016 EV with 90,000 miles, roughly 50% DCFS, and about half of its life in a temperate climate. Nearing 10 years and just under 3% degradation.

Not something that can be bought at a store yet, but they do have two restaurants lined up in the US serving it on a limited basis, one in Portland, OR and another in Austin, TX.

Interesting to see how much of a difference the study showed between vegetarians and non-vegetarians taking the same supplements and performing the same workout routine. Vegetarians had a gain of 2.4kg of lean muscle mass while the non-vegetarians had a gain of 1.9kg of lean muscle mass. That is a substantial difference, will be quite curious if similar results are replicated in further studies.

Still, the conclusion is that people on a vegan diet are not deficient in creatine but some extra (3-5 grams/day) could be beneficial in boosting memory later in life and help with muscle development/fatigue.

The phrase I have in repeat in my head after hearing it several years ago is, “This will be the coolest summer of the rest of your life.”. A stark reminder of the collective action and adaptation needed.
