Mica Sheet for EV Batteries: Superior Thermal Management and Insulation
Product Overview
Designed to optimize thermal regulation within EV battery packs, the Mica Sheet efficiently disperses heat and reduces the risks of thermal runaway—a prevalent issue in lithium-ion batteries. Its inherent thermal resistance ensures the battery operates within its ideal temperature range, enhancing safety and significantly improving battery efficiency and lifespan.
The Mica Sheet also excels in electrical insulation, providing a robust barrier against electrical leaks and short circuits, thereby further safeguarding the battery's integrity. Its exceptional insulation properties help maintain the battery's efficiency and avert potential electrical hazards.
