Not only is this not a question but the numbers given don't add up to nearly half a million pounds.

Also that weight is not "typical". That's roughly the weight of the larger (77kWh) battery pack of a Kia EV6 - a somewhat large vehicle.

Also, saying “must process ~25,000 pounds of brine“ suggests something much more intensive than “drying a saline solution in the sun”.

One does not "dig up" brine. And I'm pretty sure most of it gets recycled.

How does this compare to a non-EV?

Or it can be extracted from sea water, or it can be extracted from used batteries that are being recycled.

As the tech scales up worldwide, recycling will be a major factor in creating a closed loop (i.e. sustainable) system with the resources that are extracted.

One company working on the recycling end of this is Redwood Materials: https://en.wikipedia.org/wiki/Redwood_Materials,_Inc.

Sorry, to clarify where are you getting your numbers? I've no horse in this race but I'd like to follow along.

I am normally more interested on their carbon footprint:

Have you looked at the numbers for an ICE vehicle?
