Flame Retardants Deep Inside the Cell: The synergistic effect of high heat-resistant ceramic-coated separators and phosphorus-containing flame-retardant electrolytes enables immediate pore closure and ion channel blockage at 160°C during nail penetration tests, achieving no smoke emission from single cells and zero thermal runaway propagation in modules. This provides dual insurance for lithium battery flame retardancy at both the cell and battery pack levels.
This report reveals how adhesives and flame retardants work together in new energy vehicle battery packs to block thermal runaway within 5 minutes, truly elevating the fire safety of electric vehicles.
Lightweight Battery Pack Flame Retardant Solution: High-toughness PA6 base compounded with halogen-free flame retardant, achieving UL 94 V-0@1.5 mm, passing 150°C hot box and nail penetration tests, one-stop solution meeting all requirements of new energy vehicles for low smoke, non-toxicity, and high GWIT.
