I'm not so sure about this assessment.

But one thing I would agree with is that Li ion is not the ultimate battery chemistry.

Several others with greater density, increased cycle counts, and more readily available minerals are in development.

Of course there's BYD, which was a battery company before an EV maker:

And a survey of upcoming chemistries and technologies:

Just another indication of why we should have started emphasizing battery electric power, and the chemical research into possible solutions, 50 to 75 years ago when the problem of CO2 altering the atmosphere became scientifically indisputable.
