Lithium Iron Phosphate (LFP) are one way to continue to drop battery pack prices. I found this interesting MIC Tesla Model 3 With LFP Batteries Reveals In Tests What's Happening It appears with the current CATL chemistry tesla is having trouble figuring out the state of charge. I believe this a temporary problem that can be corrected probably with software, or at worst some extra hardware in the battery pack. The bigger problem seems to be slower charging. We know some LFP chemistries can be charged rapidly and if faster charging is needed they may need to change things. Still if the owner is mainly charging at home a 250 mile LFP BEV probably can deal with limitations. My american built model 3 now preconditions the pack if I am going to be supercharging, and allows max of 250 kw. These LFPs could be preconditioned and a 50 kwh pack probably is down to less than $6000. I think if you put it in a sub $30,000 bev people will put up with preconditioning and 75 kw charging with larger packs using the lighter faster charging chemistries.
