Featured SIAC EVs getting solid state batteries

Meh, it is another solid-state-battery gimmick.

Solid-state batteries are very difficult to manufacture, and they don't cycle well. Performance improvements are also becoming more incremental with the standard batteries advancing.

I will wait until the major players like Toyota, QuantumScape, and Samsung start making solid-state batteries, but even then, I don't expect major entry into the market until 2035.

 

funny you should mention Toyota and waiting for them.
It wasn't too long ago Toyota already hyped up their over promising - resulting in under delivering on solid state

Correct. As I said, they are hard to manufacture, as they require a lot more precision, and don't cycle well, as the solid-state electrolyte, which also serves as the separator between the anode and cathode, cracks and/or loses contact with them during cycling.

Don't expect the smaller players to beat the bigger players. Sure, you can make a solid-state battery and put it in a car, but that doesn't mean that it will cycle well and/or be cost-effective. It's not to mention that the heavy pressurization plates that are needed to ensure contact with the solid-state electrolyte by sandwiching the pouch cells reduce the claimed energy density significantly.

So, yes, the technology is still far from being mainstream if ever. I'll give it another five or ten years and then see what happens. Meanwhile, the standard cells will keep getting better and cheaper.
