Being packed away in a static location has much lower energy density requirements than driving around with the battery on-board. Getting the most out of them and then reprocessing the materials seems better than just reprocessing right away once they're no longer useful for EVs.

Exactly, it goes from being about the capacity:weight ratio to capacity:cost and as a bonus also postpones having to use powernto recycle them (and hopefully it'll be cheaper/more efficient to do so then).
