No, the cells themselves are fairly standard and built by third parties (Panasonic, LG, CATL), just co-located in Tesla's factories.
The battery packs themselves have been pulled apart and studied by everyone, pretty much all EV manufacturers are doing similar things anyway, so no real special sauce anywhere anymore.
Now there are more mature EV players in the game, innovations are happening from many manufacturers now (not just Tesla leading anymore) and then everyone else converges on the best ideas.
