Electric Vehicle smashes another record
	
	
		Agree with Mick here - although there are compounds slightly more reactive than lithium that could potentially give more energy, they also come with stability issues - lithium is a pussy cat compared to these.  NASA played with hydrogen batteries back on the 60’s and 70’s - they were very light and packed a punch, but sneeze on them and they detonated.  Don’t get me wrong, I’m not bagging out EV’s or anything - I think my thoughts on them are well known but I also understand Chemistry quite well and there won’t be another quantum leap in batteries, just the refinements like already linked with marginal improvements.  Lithium was the quantum leap and it is brilliant, we’ve only been using the tech for a short time, things will improve over time, with charging, manufacturing costs, stability, etc but don’t hang your hat on a technology that is a leap forward again like lithium was to lead acid.
I’ll link an interesting video which explains the chemistry when I’m back at my computer.
