> almost all the batteries are produced for and used in electric cars

I'm not convinced. I tried a back-of-the-envelope calculation, but there were a few too many variables, but I think the 1.5 billion smartphones sold each year edge out EVs (my main difficulty was comparing smartphone battery EV battery)

From a little Googling, it seems like an EV battery is four orders of magnitude larger than a smart phone battery, so about 150,000 EVs sold per year is the rough equilibrium point (that’s four orders of magnitude lower than your 1.5B figure), and it seems like we’re selling about a million EVs per month, at least as of the end of 2021.
