>Lithium on paper has better energy density because of where the element sits on the periodic table. Sodium is pretty close though. So, it's unlikely to push lithium out of the market for a lot of use cases. With less thermal management problems, maybe the packaging of sodium-based batteries may end up turning better (lighter, more compact) than lithium ones. That is a way how in theory it is worse, but in practice it isn't so.
