I thought LiFePO4 is a lot less energy dense then LiIon, to the extent that it is probable only really useful in fixed location applications (home battery backup, solar/wind time smoothing). Which is all great stuff, but not really going to make a low cost EV.
Am I wrong about that, or is the research towards bringing the density up?
Hmmmm, at first blush that doesn’t do a lot for me. Then I skimmed it, and ok, yes it has been “just a few short decades away” for decades. But as it says we have shaved a decade or two off of that time horizon. Which i since.
Then my pessimism caught up, (1) it is basically just asking people when they think it will happen, not actually citing any particular reason it will happen. Not even “we spent a huge amount of money so surely now! (aka I’ve been putting money into the slot machine for an hour now, surely any minute now I’ll win it all back!)”, and (2) if it has taken ~40 years to go from “2-4 decades” to “1.5-2 decades” that means in another 80 years it will only be five years away!
I’m not sure we are going to make it 80 years without cleaning up our climate act. Granted, maybe we will clean it up without some sort of ultra low pollution energy source we can basically just replace our current energy sources with and carry on much like we always have.
Well, hey, I guess at least me estimating 80 years beats me estimating “never”, so that is something?
