Key Growth Drivers

1. Stricter Global Battery Safety Regulations Governments and regulatory bodies are introducing more demanding battery safety requirements. China's GB 38031-2025 regulation requires electric vehicle batteries to demonstrate zero fire and zero explosion for at least two hours following a thermal runaway event. Similar safety frameworks are emerging across North America and Europe. As a result, manufacturers are increasing investments in advanced thermal barriers, fire-resistant composites, and battery containment technologies.

2. Growth of High-Energy-Density Battery Chemistries The widespread adoption of nickel-rich battery chemistries such as NCM811 and next-generation lithium-ion cells is increasing thermal management challenges. These batteries provide higher energy density but also generate greater thermal risks under failure conditions, creating strong demand for advanced shielding materials capable of withstanding temperatures exceeding 1000°C.

3. Expansion of Electric Vehicle Production Global EV production continues to expand rapidly across passenger vehicles, commercial fleets, and energy storage applications. This growth is increasing demand for: • Cell-to-cell thermal barriers • Pack-level fire protection systems • Aerogel-based insulation materials • Ceramic-filled composite shields Manufacturers are therefore integrating thermal containment solutions directly into battery pack architecture from the earliest design stages.

Market Trends Shaping the Industry

• Mica-Free Material Innovation: Suppliers are increasingly replacing traditional mica-based solutions with advanced fiber composites and aerogel technologies. • AI-Driven Safety Validation: Automated testing systems utilizing artificial intelligence are accelerating certification processes and improving thermal event monitoring. • Cell-to-Pack Architecture Adoption: The transition toward cell-to-pack and cell-to-body battery designs is increasing demand for localized thermal containment solutions. • Lightweight Composite Development: OEMs are prioritizing lightweight thermal protection materials that improve both safety and vehicle range.
