Sodium ion cells are already in the works with 50,000 cycle ,and sub zero performances with 10+C charge rates thatsv6 min from zero to 100% and they can and do 100% DOD cycles with ease. The only metric lacking is energy density they already kill Lithium with power density. For a plug in hybrid energy density is less critical. The very best sodium cells are now in the 160wh/kg range and that’s firmly in LFP territory so even 200 mile EV ranges is on the table. A 200 mile EV with 10C charging only needs a 6 min charge every 3 hours of drive time at 65mph avg speeds. What’s more important is most people don’t drive 200+ miles per day so a L2 top up at night is all that’s needed for 99% of all daily users. Having 50,000 cycles in a 200 mile car is millions of miles ten million to exact so mileage life is moot it’s calender life and sodium cells are 20+ year cells. This tech is here and is being ramped up. The personal electronics and power tool markets alone make sure these advanced cells get produced EVs are a much smaller secondary market. This company is specializing in bulk grid level cells the fundamental anode and cathode chemistry is relevant for consumer devices and EVs as well.

I foresee a near future where every motel in the world will have a charger at every parking spot that comes with the room and is included with the price.
