I don’t think the floated change to LFP will be for better range. It will impact the SR battery pack (not the ER), will result in a heavier pack (probably SR pack comparable weight to ER pack), and lower cost to Ford. Advantages will be: LFP can charge to 100% frequently, without battery degradation (so I suppose “usable” range would be increased, compared to regular charging to only 80% or 90%). Also, the number of lifetime charging cycles is greatly increased (LFP=“million mile battery”). Also, safety: LFP batteries don’t rapidly release energy when punctured- no battery fires! Finally, there is the potential for faster charging, if the LFP pack is more resilient under abusive charging rates.Will ever change battery chemistry? To get better range.
A couple other likely impacts of the new SR LFP packsI don’t think the floated change to LFP will be for better range. It will impact the SR battery pack (not the ER), will result in a heavier pack (probably SR pack comparable weight to ER pack), and lower cost to Ford.

All of this would apply only to the SR pack, as Ford has announced no intentions to change the chemistry of the ER pack.
