When flames engulf the battery pack, a "skin" merely 1 millimeter thick is rewriting the rules of safety. From the gas-silicon "super shield" that withstands 1,300°C infernos, to phase-change materials that intelligently regulate temperature like human perspiration — the logic of battery safety has been completely reshaped: from passive defense to system "self-healing." This invisible film of wisdom is silently safeguarding the future mobility revolution from electric vehicles to flying cars. With over 15 years of experience in new-energy composite material R&D, she has undertaken more than ten national and provincial-level scientific and technological projects, and filed nearly 100 patents. Dr. Cao Xiaoyan leads her team in breaking through world-class challenges in nano-functional composite materials for battery thermal-runaway protection, with full-scenario adaptability far exceeding national standards. Her founded company has been recognized as a National High-Tech Enterprise and a
