Cheap, high longevity, high capacity. You can't have all three.
What's better depends on application. I don't want a cheap battery in my car if I only get 80 miles on a charge.
you can get as much range as you want with just making the battery bigger.
Go reread the thread. You're (hopefully unintentionally) arguing against using sodium batteries for grid storage because lithuim has more energy density.
Cost, high longevity, and heat tolerance are way more important for grid storage than energy density. Sodium batteries are perfect for that, and were poised to start being supplied for that application until the price of lithium tanked at the start of the year.
Also, the sodium batteries that are (and were) about to go to market have enough energy density that manufacturers were considering adding them to cars by mixing and matching sodium and lithium cells in varying ratios to match various use cases. The two chemistries aren't mutually exclusive in any field
