I'm honestly confused about this + Tesla's free access to patents.... Does this mean that everyone has access to a 4680 battery now by just asking LG Chem for them?
LG would need to be using similar tech to tabless electrodes to create the larger cells and not run into thermal problems. Only Tesla is currently set up to use the larger cells - so any other OEMs would need a long lead time to redesign their pack.
Tesla is probably too good a customer for LG to slight in terms of ripping off their technology, so if LG are creating the larger cells and selling to other OEMs they probably have Tesla's consent.
That said, there's probably several ways to create the effect of tabless electrodes while getting around patents - so I doubt Tesla could stop LG creating similar cells should LG be determined to do so.
