Aerogel Fiberglass Blanket for Battery Safety in New Energy Vehicles
Date: 2025-05-27 Categories: News Hits: 155
1. Background
As energy storage and electric vehicle (EV) technologies continue to evolve, battery safety becomes a top priority. Recent battery thermal runaway incidents have highlighted the critical importance of integrating advanced thermal insulation and fire-resistant materials into battery systems. In response to these challenges, our Aerogel Fiberglass Blanket provides an innovative solution to protect against heat, fire, and structural failure in EV battery modules.
2. Product Advantage
Our Aerogel Fiberglass Blanket stands out in the industry for its combination of ultra-low thermal conductivity, lightweight structure, and extreme flame resistance. It has officially passed the highest UL fire resistance certification – UL94-5VA – a level that very few thermal materials can achieve.
Key Advantages:
· - UL94-5VA Certification: Withstands direct flame without hole penetration
· - Excellent thermal insulation: Thermal conductivity as low as 0.018 W/m·K
· - Non-combustible, low smoke, non-toxic emission
· - Lightweight and flexible: Adapts to compact battery pack designs
3. Application in Battery Packs
The Aerogel Blanket is typically applied between cells or modules in power batteries to prevent thermal propagation. It can also be used as an external wrap for battery modules, offering both thermal insulation and fire barrier properties. This significantly delays or prevents thermal runaway, giving valuable response time in case of failure.
4. Why Thermal Runaway Protection Matters
Thermal runaway in lithium-ion batteries can lead to chain reactions, causing fire, smoke, explosion, and severe equipment loss. In the event of a single cell overheating, a lack of thermal barrier can lead to the failure of the entire pack. Our solution isolates heat and prevents propagation, forming the last line of defense before failure spreads.
5. Technical Standards & Certification
The material meets the following international standards:
· - UL94-5VA fire resistance (top-level UL certification)
· - ROHS / REACH compliance (no harmful substances)
· - GB 8624-2012 A1 non-combustibility rating
· - Thermal performance tested per ASTM C177
· - SGS ELV Test Reports
· - SGS-Chemical film-forming aerogel fireproof thermal insulation felt Inspection report
· - The Test Center of CAAC：Determination of Burn Through Resistance Characteristics of Thermal Acoustic Insulation Materials
· - The Test Center of CTCNJ: Overall test report of chemical film-forming aerogel felts
· - IATF Quality Management Certification
