Cost is no longer a concern as today LFP batteries and electric motor price is cheaper than an ice engine in China. Though my main point is that there is a lack of infrastructure to charge at full speed current batteries so higher capacity faster charging solid state batteries are mostly pointless when you cant charge them fast or to full capacity.
It's still a major expense. Reducing costs is good.
Higher capacity and faster charging doesn't have to actually mean more capacity and faster charging. It can mean smaller and lighter for the same capacity and charging speed. If you have a technology with 10x the energy density, you can build a car that goes 3000 miles on a charge, or you can build a car that goes 300 miles on a charge and has a battery only 10% the size/weight. (In practice a even a bit less than that, since the reduced size/weight will reduce how much energy you use per mile.)
