In mass production this year in China will be 160 wh/kg Sodium Ion and the company claims it can be 90-95% density cell-to-pack because sodium ion is like LFP: doesn't require as much safety stuff as the nickel-cobalt chemistries (which reduces pack density to only 60-70% of the cell density).
That's (based on current reputed pack densities of Tesla Model 3 SRs) good enough for the 300 mile consumer BEV. As in, the city car for a huge percentage of the world population.
I believe the roadmap is to get sodium ion to 200 wh/kg in a couple years, with good CTP yield means 400 mile cars like Model S. NO LITHIUM. NO NICKEL. NO COBALT.
Sodium Sulfur will probably happen in another 10 years based on papers. That may offer 400-500 wh/kg IIRC.
