I don't think there are batteries that meet Toyota's durability standards.

Toyota wants their cars to be able to last a million miles in extreme environments (-40 degrees Alaska, +120 degrees F deserts). You can't do that with today's off-the-shelf battery technology.

Gas cars can't go a million miles on one engine, either, and need endless maintenance. EVs already get past a few 100k miles with much less work. EVs will be first to 10^6 miles.
