The RECYBAT project aims to develop a specialized platform dedicated to second-life battery applications. Controlled testing is underway to better understand aging mechanisms and their impact on battery safety.

A collaborative initiative driving energy innovation

Launched in May 2022, RECYBAT brings together:

  • SAS CRITT M2A

  • CREPIM – Material and Fire Test Expert

  • UMET - ISP (University of Lille – Materials Science Laboratory)

CRITT M2A’s expertise within RECYBAT

At CRITT M2A, we focus on:

  • Battery health diagnostics

  • Aging and abuse testing

  • Technical data analysis and contribution to the scientific understanding of battery technologies

A case study on Samsung 53G (NCA chemistry) showcases the State of Health (SoH) evolution of battery cells.

Key findings from the testing phase:

  • As batteries age, results show increasing dispersion, particularly in advanced aging stages.

  • Some cells become inactive despite maintaining SoH levels above 85%, due to CID (Current Interrupt Device) activation, marking end-of-life.

  • Cells cycled at 0°C exhibit an abrupt shift in degradation rate, likely caused by lithium plating. Ongoing post-mortem analysis will offer further clarity.

Continuing the experimental campaign

The testing continues with follow-up abuse tests to deepen our understanding and support the technical challenges of battery reuse and second life.

This project is co-financed by the European Union.
