Lyten (Silicon Valley startup up) has shipped new generation batteries for military applications. It has shipped A0 parts to several automakers.

High density Si anodes are progressing. Group 14 as an example.

Solid state batteries are in AO samples.

To my view Lyten is closer to high volume manufacturing (90% yields using current production equipment with a 4% modification. And lowest price.

Could all of these fail. Sure but so far progress.
