You'll get better info searching on the NEV thread, and I'm not an expert on this either. But to summarize quickly in terms of the technical stuff, CATL and BYD got ahead of the South Korean competitors because of 2 reasons: 1) LFP batteries & 2) structural battery packs (both CATL and BYD have this).I do wonder how SK and LG's batteries compare to CATL/BYD/Tesla.
I haven't followed the NEV thread as closely as the Semi thread, do you know if there's any good comparisons?
South Koreans didn't adopt LFP into production until sometime this year I believe. Just ternary battery before.
Ford is looking for LFP so SK On should be providing it by then.
