>Batteries likely last 20 years and afterwards another 30 years as energy storage devices.
Out of curiosity, do you have a citation for 20 year old EV batteries being able to be repurposed for another 30 years? Assuming they are used for gridscale storage, 30 years could very easily be 10,000 charge-discharge cycles (thats slightly less than one per day).
LFP batteries have a much longer lifespan that lithium ion, but in a brief search I cant find any claim that they will last a half century. For example, this article [1] says LFP batteries have a "calendar aging" rate (capacity loss independent of active charge cycling loss) of "ca. 0.2 percentage points of capacity fade per month at 25°C and to ca. 0.5 percentage points per month at 50°C". So, in ideal conditions a battery that is kept in storage would take 20 years to reach half capacity and 40 years to reach zero capacity. Presumably daily charge-discharge cycles would reduce that lifespan significantly.
Your numbers are empirically wrong. If they were right my own LFP EV should have now lost 5%, but it hasn‘t.
One discharge cycle per day is utterly insane. Nobody does that. How many people drive 350 miles EVERY day for 30 years? 350 miles - that’s about one discharge cycle.
I will only reply to your last paragraph:
