[EV Battery Thermal Management Materials – Product Features 

 

Thermo-Guardian Sheet: The thermo-guardian sheet is an advanced thermal management material aimed at improving safety in electric vehicle battery systems by serving as a thermal runaway retardant, installed internally in battery packs to halt the rapid spread of heat or fire. 

 

[Key Features] 

  • Special flame-retardant coating provides excellent fire suppression, safeguarding battery modules during critical situations. 

  • Exceptional heat resistance enables reliable performance under extreme thermal conditions, with continuous operation up to 1000 ℃ and peak resistance of 1200 ℃. 

  • Superior electrical insulation is essential for ensuring the safe operation of battery systems. 

  • Temperature Control Protection enhances battery safety by maintaining the opposite surface temperature below 300 ℃ during a fire event. 

  • Certified performance meets the UL-94 V-0 flammability rating and 8.0 kV/mm dielectric strength, ensuring reliability and compliance with safety standards. 

 

C2C (Cell-to-Cell) Pad: 

The C2C Pad is an advanced solution for inter-cell thermal management that improves heat dissipation and enhances safety in battery modules. It is installed between cells to optimize battery performance while maintaining safety and structural integrity. 

 

[Key Features] 

  • Excellent lateral heat dissipation allows for even temperature distribution among cells. 

  • Outstanding inter-cell insulation offers flame retardancy and electrical insulation, ensuring protection against thermal and electrical hazards. 

  • Mechanical protection is essential for enhancing durability by safeguarding against internal vibrations and external impacts. 

  • Slim Design enhances space utilization, enabling greater energy density in compact battery packs.
