Product Description

EV Battery Mica Sheet Optimal Thermal Management Solution

Product Overview

The Mica Sheet is engineered to optimize thermal regulation within electric vehicle battery packs, efficiently dispersing heat and minimizing the risks associated with thermal runaway—a common issue in lithium-ion batteries. Its natural thermal resistance ensures that the battery operates within its optimal temperature range, thereby improving safety and significantly enhancing battery efficiency and lifespan.

The Mica Sheet also plays a vital role in electrical insulation. It creates a robust barrier against electrical leaks and short circuits, further enhancing the battery's integrity. Its outstanding insulation properties help maintain the battery's efficiency and prevent potential electrical hazards.
