Multifunctional fire retardant coatings could be coated on various metal substrates to effectively decrease the heat transfer rate, control the direction of fire spread, slow down heat diffusion, and protect substrates from damage. Ultimately, this would enhance the safety of lithium-ion batteries during thermal runaway. In this study, a series of modified multifunctional fire retardant coatings were designed and developed by nanometer-structured fillers, such as graphene oxide (GRO), carbon nanotubes (CNTs), and inorganic silicate nanotubes (ISNTs). The results showed that the ISNTs-modified multifunctional fire retardant coatings could improve impact resistance, electrical insulation capabilities (leakage current was lower than 1 mA under a direct voltage of 6 000 V for 60 s), and fire resistance performance (during a 30-minute fire burning at 1 000-1 300 ℃, the maximum temperature on the noncoated side was below 349 ℃), while reducing the pigment-binder ratio of the system.
