Battery manufacturing has to be at massive scale even in a nuclear powered world, just to supply battery electric vehicles.
Converting every passenger car and light truck in the US to a BEV would involve enough batteries to store something like two days of the average grid output, which is more than would be needed for a cost optimal wind/solar/battery/hydrogen system for a 100% renewable grid.

Assuming the power stored in these vehicles can be reclaimed by the grid anytime they want?
No, I was just pointing out the scale of the required battery manufacturing.
It's an argument I like to use. When someone claims "we can't use X because of reason Y, we have to do Z instead" I look to see if Z also is hit by objection Y.
Another example of this is "renewables require too much material that we can't recycle", at which point I observe that the quantity of materials produced by society as a whole greatly exceeds what renewables would involve, even if the society is powered by nuclear. The US produces 600 megatons of construction and demolition waste a year, for example. Renewable waste would just be a minor blip on this existing waste stream. So, either recycling this waste isn't actually needed, or a putative sustainable nuclear-powered society has discovered how to recycle it, so just toss the renewable waste (which is almost entirely things like steel, aluminum, and glass) into that same recycling infrastructure.
