140 wh/kg is comparable to the LFP batteries used in SR model 3s in Tesla, so that implies a 300 mile EV car with no lithium.
Yes it missed the 2022 date, but "planned production" is far better than "hey check out this research paper".
140 wh/kg should enable nearly all modes of day-to-day city and suburban driving. IMO that is a HUGE deal since that is a very large percentage of daily miles driven. I believe it is quite safe, having reduced safety/cooling like LFP which helps close the gap at pack level density with cobalt/nickel chemistries.
But ... we'll see. But 200 wh/kg LFP (which should be 300-400 mile range cars and SUVs) combined with sodium ion for the "lesser" packs should enable a true BEV revolution at least in consumer cars.
That would leave solid state / cobalt-nickel / sulfur for long distance trucking and other applications. Even if solid state makes it to market in the next couple years, I predict it will not be price competitive with Sodium Ion/LFP techs for quite a while after that. There will be plenty of buyers for practically all battery chemistries I would imagine.
