Abstract: The present disclosure discloses a phase-change flame-retardant fiber material for thermal management of a lithium ion battery in a closed space and a preparation method. The phase-change flame-retardant fiber material is prepared in a coaxial electrostatic spinning manner and includes a composite phase-change fiber material PASA-TPU at a core part and a flame-retardant fiber material TB-PAN wrapping a surface of the core part. The composite phase-change fiber material is well wrapped with the flame-retardant fiber material, and the lithium ion battery wrapping the whole phase-change flame-retardant fiber material in the closed space is subjected to charge-discharge cycle; the result shows that the surface temperature of the battery can be effectively reduced by about 20° C. by the material, and the material can effectively play a role in multiple cycle processes; the whole material has an excellent and stable heat absorption effect, and has no leakage and collapse; and the phase-change flame-retardant fiber material only has thermal shrinkage and blackening phenomena and is not combusted after being ignited by open fire for over 20 s. Therefore, the phase-change flame-retardant fiber material of the present disclosure has a relatively good flame-retardant effect compared with other phase-change materials.

Abstract: Compositions with improved flame properties and with improved melt dripping properties can include a first polymer and a reactive component. The first polymer may be nylon or polyethylene terephthalate (PET). The composition can be formed into fibers and woven into a fabric. Crosslinking of the first polymer or of the first polymer and the reactive component can provide the improved properties.
