The Second-Life Battery Economy:
Forging a Reliable Market for EV Pack Repurposing
The emergent "used EV battery" market is stalling. Despite the hype, technical degradation patterns, valuation asymmetries, and regulatory ambiguity are creating huge stranded-asset risks for auto makers and grid operators.

The "Lemon Market" Thesis
Enterprise buyers are currently flying blind. While circular economy investors see upside, the market mechanism is broken. Without a trusted, forensic standard for State-of-Health (SoH), high-quality used packs are indistinguishable from degraded ones, driving prices down to the level of the lowest-quality assets.
