There's a right mix of density/weight that can push things in favor of solid state. For example, if they need less or no cooling and have LFP like lifecycles, then you could see really interesting things in terms of the range. All the sudden a 50kWh solid state battery might compete in range with a 80kWh LFP due to the massively reduced weight. This all remains to be seen though. CATL I think is one of the only manufactures signalling mass production of solid state batteries but it's sort of a "believe it when I see it" situation. (Ditto with sodium batteries).
