Electrolyte Corrosion Resistance Testing and Lifetime Prediction of Battery Insulating Flame-Retardant PP Extrusion Components

Introduction

As electric vehicle (EV) and energy storage systems (ESS) grow in demand, the need for high-performance insulation materials in battery modules becomes crucial. Battery insulating flame-retardant PP is widely used in battery enclosures due to its lightweight properties, electrical insulation, and resistance to flame propagation.

Testing Methods for Electrolyte Corrosion Resistance

• Immersion Testing: PP specimens are immersed in battery-grade electrolytes at elevated temperatures to analyze degradation.

• Electrochemical Stability Testing: Measures ionic conductivity and dielectric loss over time.

• Thermal Aging Tests: Simulates long-term degradation under operating conditions.

Predicting the Lifetime of Battery Insulating PP

• Arrhenius-Based Lifetime Prediction: Estimates long-term performance using accelerated thermal aging data.

• Finite Element Simulations: Models electrolyte penetration and predicts failure rates.

Conclusion

By integrating electrolyte resistance testing, advanced material engineering, and AI-driven predictive modeling, manufacturers can develop more robust and long-lasting battery insulating flame-retardant PP solutions.
