What does this research mean for the field?

The safe and reliable deployment of second-life batteries in the power sector requires an aging-pathway-aware thermal-safety grading framework, as thermal safety depends on the specific aging pathway rather than just the state of health. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Evaluate technological, thermal safety, and regulatory barriers to repurposing retired electric vehicle batteries for grid-scale energy applications.

Implication

Review demonstrates non-linear thermal runaway risks in second-life electric vehicle batteries, highlighting the need for aging-pathway-aware safety grading and adaptive thermal management.

Key Points

Evaluate technological, thermal safety, and regulatory barriers to repurposing retired electric vehicle batteries for grid-scale energy applications.
Reviewed literature across state of health (SoH) predictive modeling, thermal management systems, and regulatory policies.
Assessed battery degradation mechanisms and thermal runaway vulnerability across different cell aging pathways and abuse conditions.
Thermal safety does not follow a monotonic relationship with state of health, as mildly aged cells can show higher thermal runaway susceptibility than fresh or deeply aged cells.
Proposed an aging-pathway-aware thermal-safety grading framework coupled with safety-adaptive thermal management to enable safe, large-scale deployment.
