Currently it probably makes the most sense to mass produce non plug in hybrids with tiny NiMH batteries, kind of like the first gen prius.
At least NiMH batteries can be easily recycled.
In the US if we try to sell even 1% of new vehicles with large batteries the battery materials producers can't handle it and raw material costs go crazy.
