Driving with something that power dense is incredibly dangerous. You’re literally driving a bomb, dynamite is 4.6 MJ/kg

Calling them BEVs is misleading and damaging to EVs as a whole, because you’re right, batteries do have their limitations, at least today’s batteries. The proper industry term is FEV, fully electric vehicle. Choosing to limit EVs to only batteries is an arbitrary decision made for argument’s sake, but instead of looking at how they can be improved, you’re just focusing on why it’ll fail. A “battery” is anything that stores energy, not just the traditional battery, and once EVs are the norm, they probably won’t be using LiPos, they’ll be using something that hasn’t been invented yet.

@Hypx Yes transistors are smaller and faster, that’s the literal definition of Moore’s Law. But a transistor today is a smaller, faster version of the exact same technology as the first transistor, applying a small signal to pass current between doped semiconductor junctions, the only major difference being changing the semiconductor from germanium to silicon.
Batteries, however, are fundamentally different from when they were first invented. Yes, it’s still storing electrical energy as chemical energy, but the chemistry has changed so much since the first batteries. The word “polymer” wouldn’t even exist for another 20 odd years. And new technology is constantly being discovered, such as solid state batteries or supercapacitors.
And if you want to talk about physical limits, Moore’s Law is essentially dead. We’re nearing a point where you’d have to split atoms to make a smaller transistor. Batteries are limited by their chemical makeup, transistors are limited by the laws of physics.

@Hypx There’s no Moore’s Law for batteries because they’re a different technology. Transistors today are still fundamentally the same as the first transistor, made in 1947. Batteries, on the other hand, are constantly evolving. The first LiPo battery wasn’t invented until 1997, and there are multiple new battery technologies currently being studied, like solid state batteries.
