Note that if doing a LFP battery, then you don't have the Cobalt issue. Also, as I could most recently find, prices on LFP are such that currently it could be about $7,000 for a pack that can get over 200 miles in a typical EV. CATL claims they'll have it under $4500 for that capacity battery pack by the end of this year. Analysts are suggesting that 2025 might see that battery pack go under $2800 or so. If that comes to pass, then it's a slam dunk that an EV will incur less cost over a decade than the ICE maintenance and repairs, even ignoring gas vs. electricity costs.
The price has been coming rapidly down, after the shortages have subsided. Of course, whether the supply chain and pricing of the big automakers reflect this... well we have to see. However, Ford at least proclaimed they "managed" to save $8,000 cost per unit of mach-e, and most of that is likely just the battery pack getting thousands of dollars cheaper (they also redid the rear motor and other touches, but the bulk of that number is probably just battery cost reduction).
