I still remember in 2016 when Elon Musk made a big announcement about his "acqui-hire" of the Dalhousie University EV battery research team led by Dr Jeff Dahn. There was much fanfare and announcements of million-mile batteries and 3% increase in energy density every year. Moving on from miracle batteries to Thai rescue to Hyperloop tunnels and presently to data centers in orbit.
We was an electronic music producer in-between and a pro-level gamer. Let's not forget these achievements, either.
Elon is a fraud but Jeff Dahn and Dalhousie are legit.
Lithium batteries have been increasing in density at about twice that rate for the last decade. And million mile LFP batteries are available, NCM is nearing that benchmark.
All credit to the people who actually research and build them which is not Elon, since Tesla don't even produce the majority of their own battery usage.
