In the rapidly evolving new energy vehicle industry, power batteries are crucial, with their performance directly impacting the vehicle's capabilities. Ensuring safety, particularly from thermal runaway, is vital. Mica materials offer significant benefits for power batteries due to their key properties:
High Voltage Resistance: Mica's excellent voltage resistance (20 kV/mm) ensures stable operation in battery systems without material degradation from high voltage, as seen in mica tape used in fire-resistant cables that can withstand extreme conditions (BS6387 standard).
High Temperature and Fire Resistance: Mica's thermal insulation and UL94 V-0 flame retardant properties help manage the heat generated during battery operation. In case of heat buildup, mica can prevent thermal runaway and fire spread, adding a critical layer of safety.
Good Processing Performance and Adaptability: Mica's adaptability to irregular surfaces and its ease of processing make it suitable for fitting into various battery components. Soft mica rolls can conform to complex shapes, while hard mica plates are used for structural components like bottom plates and covers.
Lightweight: Mica's low density, lower than aluminum, supports the lightweight design trend in new energy vehicles. This reduces battery weight, lowers material costs, and enhances battery life, crucial for extending vehicle range and maintaining performance.
Overall, mica's combination of high voltage resistance, thermal and fire resistance, adaptability, and lightweight properties make it a valuable material for enhancing the safety and performance of power batteries in new energy vehicles.
