That is true, but my small EV the batteries are 500kg, same car with combustion engine only has 40L fuel tank.
Stability is important, but lithium-ion ain't really that stable either. Still waiting some solid state to get made.
Yeah, lithium ion is a good stopgap while we develop better options, but it's by no means stable. Get them too hot or puncture a cell and you're going to have a bad time.
