Why Degradation and Safety matter

Understanding how and why batteries fail is essential to improving their performance, lifespan, and safety.

At CIC energiGUNE, we provide a comprehensive service that helps manufacturers, integrators, and end users to:

  • Identify degradation causes and failure modes
  • Validate chemistries under realistic conditions
  • Anticipate and prevent safety risks

Our integrated expertise bridges research and industrial needs, supporting reliable and safer batteries for mobility and stationary applications.

Our Value Proposition

  • Controlled Cell Opening

    Controlled Cell Opening

    We perform controlled cell opening to safely examine internal components and identify degradation causes.

    • In-depth analysis of cylindrical, prismatic, and pouch cells
    • Non-invasive imaging with microCT for internal structure insights
  • Advanced Characterization

    Advanced Characterization

    Advanced characterization techniques enable us to analyze materials and detect failure patterns for design improvements.

    • SoH diagnostics and failure mode identification
    • Structural analysis to detect degradation
  • Abuse Testing

    Abuse Testing

    Abuse testing simulates extreme conditions to assess cell safety and reliability in real-world scenarios.

    • Electrical, thermal, and mechanical stress testing
    • Thermal runaway analysis and safety assessments
