You seem to suffer from some misunderstanding. Solid state batteries advocated by companies like Solid Power or QuantumScape are lithium ion batteries. In fact the cathode materials made by Northvolt would go 1 to 1 into a QuantumScape battery.
Northvolt has actually acquired a competitor to those above and will compete in the same field (actually lithium metal anodes, not solid state).
The fact is, that even the most advanced company in lithium metal anodes (wrongly called solid state) will not have its product in 100k cars by 2025. In the years from now to then 10s of millions of BEV have to be built, and the supplier to those cars will have made billions.
And even then, all solid state companies combined will likely not produce enough for 100k in 2025 when the production rate of BEV should be running at 10+ million a year.
So it will take many, many years for solid state (li metal tech) to be a real player in the market and 10s of billions will be made by battery suppliers until then.
For them to simply wait 15 years and do nothing would be kind of crazy.

They are not even as close as Li Metal.
