Clean electricity generation paired with the first grid-level sodium battery energy storage system can bring costs down to just $0.028 per kWh. The 10 MWh storage capacity is executed with sodium-ion cells that can be charged in just 12 minutes.
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
