Those are not “better” batteries chemically or electrically. They are just cheaper and don’t use lithium which is considered a feature.

Cheaper is a kind of better.

Sodium batteries are cheaper, safer, and last longer than lithium batteries. That's exactly what you want for grid-scale energy storage. So *yes, sodium IS better than lithium* for grid-scale energy storage

Sodium battery performance is better in the cold. Currently some sodium battery products are out in the market and aren't appreciably cheaper yet and the answer to 'why' was 'cold weather performance'.
