I don’t think those are the issues. As an EV owner, I do most of my charging at home, and speed/availability of chargers has yet to become an issue. We don’t have to replace every gas station. Transportation corridors and destinations
I believe the bigger issues are supply availability for nickel, cobalt, lithium, and silicon carbide.
-Nickel and cobalt are key materials in high performing cathodes. Iron-phosphate is now being used for cheaper EVs, but the energy density is lower. Next breakthrough we are waiting for on the cathode side is iron-fluoride, which has a higher energy density, but doesn’t work outside of lab conditions yet.
-There is not enough actively mined lithium to complete the EV transition, and we are also putting it in boxes on the ground for energy storage.
-Silicon carbide chips are rapidly replacing IGBTs and MOSFETs in the engine and charging hardware, and the ramp to meet demand is going to take years
- theshrike79 4y agoI read a statistic somewhere that we do have enough metals to replace all cars with EVs. BUT, there's definitely not enough raw material to electrify all trucks, lorries, tractors etc etc. Battery tech has to take a few leaps before we can get there. But stuff has advanced crazy amounts in the last 20 years, just think of phone and RC batteries from the 90's or early 00's. A drone wouldn't have made sense 20 years ago, the battery tech just wasn't there yet - too heavy. Now we sell them as kids toys for 20€.
