there are patents and research docs on rejuvenation lithium batteries by flushing the electrolyte then replacing the electrolyte.
Some large companies holding patents including general motors. So I'm assuming the process gives good results, its based on simply flushing with ec:dc or similar electrolytes without touching the copper/aluminium in the cells at all, it removes the old sei layer,
then new electrolyte with lithium is added, new sei formed and cell is rejuvenated.
This leads to my idea for large packs:
use the electrolyte as the cooling system. Instead of using an external cooling system for the pack, make the pack in such a way that
the internal electrolyte is flowing through the cells for cooling. This would make it easy to rejuvenate the cells and extend battery life.
