Did I miss this or is this new?

Claims of a breakthrough EV battery seem to come every week or two. The reality is that it’s not so easy to bend the laws of physics. But the latest claim is offered by John Goodenough, co-inventor of the now ubiquitous lithium-ion battery and winner of a Nobel Prize in chemistry for that previous breakthrough.
Goodenough, a researcher at the University of Texas at Austin, revealed a sodium-glass battery technology last week. He told IEEE Spectrum:
Should we believe Professor Goodenough when we’ve heard so many promises about breakthrough batteries before ­– and they never seem to pan out?
Well, yes, says Donald Sadoway, a battery researcher and MIT materials science professor:


EV battery breakthrough claims are usually bull, but this guy won Nobel for lithium-ion - Electrek
