Most battery tech is just lithium ion batteries wired in series, like 80 laptop batteries. They regulate the temps so that the batteries don’t degrade too fast. Battery tech hasn’t changed much in decades, so you will see the same problems on your phone battery on car batteries. So, no, Tesla battery tech isn’t special.
I recently heard china is the first to manufacture sodium ion batteries for their consumer EVs. Sodium is supposed to be better, but I forget why.
