You are correct, and the critical number is that sodium is over 3 times as massive as equivalent lithium. But to keep in perspective, we are talking about an element that's only about 5-7% of a pack, so theoretically you could maybe get to only 10-15% more massive as a penalty for swapping out lithium. Which is some applications is still unacceptable,but broadly we have seen a lot of accepting that same tradeoff going from NMC to LFP...
