EVs no, but I think some Toyota hybrids (which are of course not even PHEVs) still use NiMH. Toyota tends to be very tight-lipped about their batteries and their sizes (or rather, lack thereof).
Tends to be tight lipped??? It is in the catalog[1]! It is more that American consumers aren't tech obsessed than Toyota being reluctant to share.
Even just looking at online media reports[2][3] clearly sourced from some exact same press event, it is obvious that US English equivalents are much lighter in content than Japanese versions. They're putting the information out, no one's reading it. It's just been the types of information that didn't drive clicks. Language barrier would have effects on it too, that Toyota is a Japanese company and US is an export market, but it's fundamentally the same phenomenon as citizen facing government reports that never gets read and often imagined as being "hidden and withheld from public eyes", just a communication issue.
I was looking up this year's Corolla a while ago and likewise there was minimal info that I could see about the battery capacity, which I think I figured out was about 3kWh.
