Second life LFP batteries are becoming increasingly difficult to justify as the price of new batteries continues to fall following a brief increase in 2022. 2023 saw average battery pack prices fall from $151/kWh to $139/kWh, though LFP pack prices were either side of $100/kWh at times due to lithium salts being the primary driver of lower pack costs. Repurposing old batteries for use in secondary applications remains a noble ambition towards implementing a circular economy for automotive batteries, but the assumptions don’t bear out in reality because as costs continue to fall new batteries will be the financially sound option. Second life batteries have a similar problem to recycling in that as battery lifespans increase through design and material…
