Challenges:

1. Thermal Runaway Risk in Batteries: If not properly managed, overheating batteries can lead to fires or system failures. Polymers must be flame-retardant, thermally stable, and durable.
2. Material Compatibility: Exposure to various chemicals, high voltage, and wide temperature fluctuations requires polymers to maintain long-term integrity across multiple functions.

Opportunities:

• High-Performance Thermoplastics: Materials like PEEK and PPS are gaining traction for their excellent dielectric strength and heat resistance in battery modules and connectors.
• Battery Pack Innovation: Use of polymers in potting, gasketing, and separators helps manage heat and insulate critical components.

Conclusion:

Thermal and chemical resilience is essential for safe EV operation. With growing battery densities and faster charging speeds, the demand for high-performance polymers in thermal management will continue to rise sharply.
