What do you mean with 'this'? You mean silicon anodes ad additives? Just to start with, silicon has almost the a very high theoretical potential for an anode.

What do you mean with 'this'? You mean silicon anodes ad additives? Just to start with, silicon has almost the a very high theoretical potential for an anode. Almost as high as lithium metal. Its not new, current a standard Tesla likely already have 5% silicon oxide in the anode. But to compete with what QS is planning you will needed higher % and likely a different form of silicon. Every large battery is working on silicon, it makes the battery cheaper and increases density. There are also a huge number of silicon startups. One example that is comparable to QS is Sila Nanotechnology. silanano.com Tesla is investing massively in silicon as well. They bought a number startups and doing a lot of development. I would suggest this playlist (just the silicon parts if you want): https://www.youtube.com/playlist?list=PLyvdbTy3v1d5luwdDGPFPab9WWPmMW_cJ https://www.youtube.com/playlist?list=PLyvdbTy3v1d5luwdDGPFP... On the same channel you can also find videos on QuantumScape that are very well researched. But just to be clear, I don't think its a 'scam'. I just think their valuation went insane for a company many years away from actually selling anything and huge investments to be made with large tech risk.
