No one is repurposing whole packs because they are only gotten rid of after they've completely failed. Repurposing individual battery cells is difficult when they're tightly integrated into a battery pack. They're welded in, and often entombed in wax, foam or adhesives. If you can disassemble down to a module level, then you have a shot. Usually when an EV pack fails, it's due to a single module going bad. There's a pretty good sized industry to refurbish failed Prius battery packs by disassembling them down to modules, and then characterizing the modules and matching them back up with similarly degraded but otherwise healthy modules across many battery packs.
