In my opinion the Battery equation is already solved. Even for those who are at the end of longer driving range curve, we have a solid and realistic roadmap of battery technology. Pick Tesla tabless battery for example. It isn't Solid Battery like Holy Grail Battery, but it gets to the point where even if you are somewhat skeptical of EV, surely this is edging close to good enough?
People often confuse range anxiety with battery capacity. I dont think that is strictly true. It is one of these things where engineers would come in and suggest we need bigger battery to solve our customer's problem. But here is an product person POV, what if you have fast charging station everywhere. From your car pack living in cities, to packing in a mall or pubic parking space. This is similar to charging smartphones. Once you can charge your smartphone even dinning in Restaurants or on a Bus. You dont get nervous about running out of battery.
So as many comment have suggested, the biggest obstacle to EV isn't battery, is the abundance of Charging station. And given I actually believe City transport in the future should be micro mobility, whether that is e-bike or something else we have yet imagined, we need charging port for both bike and EV. And this needs some government planning.
While this is all good discussion, I really wish we focus more on silicon carbide :)
I wonder why they didn't jump straight to 300mm and only upgraded to 200mm wafers. They could have completely cornered the market with better economy of scale.
