I'm curious what the temperature resiliency is for sodium-ion batteries. I had a power outage recently where I was relying on a lithium-ion battery. As the temperature in the house plunged, it because so inefficient that charging a single phone overnight drained a quarter of the battery.
If I'm not mistaken sodium ion is better with temperature and durability. The biggest problem is energy density, so they can't compete in any applications where size and weight matter. This leads to their 2nd biggest problem, which is that there's so much production infrastructure for lithium that no one wants to invest in new assemblies for other battery chemistries
