The issue is we haven't had real breakthroughs in battery tech since the 70s, we've gotten slightly better improvements but we're still using the same base. We've had tons of promises in the lab but nothing has actually made it out. Hopefully there will be a breakthrough but so far there hasn't been.
Maybe you should take a look at some these charts, especially power density and cost
There have been huge improvements
They got heavier to hold more charge. Nothing in any of these charts proves the tech has advanced drastically since the 70s. Seriously the 2nd chart just says they got cheaper basically for how much you get. That's like saying HDDs are cheaper now more than ever, but still use a spinning disk technology... it's like we never leaped to SSDs. That's the jump we need.
Did you notice the charts showing Wh/kg? Since 1991, the charge a battery can hold per weight has gone up 500%, even while prices have dropped a similar percentage. That’s huge, and that’s what makes EVs (and even smartphones) so practical now, but not back then. We have made that jump
Yes it's still not enough, that's been my whole point, all we've done is like if SSDs were never invented. Like we're still stuck on spinning disk tech. We're still lacking the charge speed and the range. Yes batteries are better than 1970s when the current design was created, but we haven't made that jump from HDD to SSD.
