Product Description

High-Performance Mica Insulation Pad for Electric Vehicle Batteries​


Product Overview

The Mica Sheet is designed to enhance thermal regulation within electric vehicle battery packs, effectively dispersing heat and reducing the risks associated with thermal runaway—a frequent issue in lithium-ion batteries. Its natural thermal resistance ensures that the battery operates within its ideal temperature range, thus improving safety and significantly boosting battery efficiency and lifespan.

The Mica Sheet also serves a crucial role in electrical insulation. It forms a strong barrier against electrical leaks and short circuits, further improving the battery's integrity. Its excellent insulation properties help maintain the battery's efficiency and prevent potential electrical hazards.
