  • Publication number: 20230282905
    Abstract: A thermal runaway barrier for at least significantly slowing down a thermal runaway event within a battery assembly. The thermal runaway barrier includes a layer of a nonwoven fibrous thermal insulation comprising a fiber matrix of inorganic fibers, thermally insulative inorganic particles of fumed silica dispersed within the fiber matrix, and a binder dispersed within the fiber matrix so as to hold together the fiber matrix. An optional organic encapsulation layer may also be used to encapsulate the nonwoven fibrous thermal insulation.

  • Publication number: 20230238600
    Abstract: A thermal runaway barrier for at least significantly slowing down a thermal runaway event within a battery assembly. The thermal runaway barrier consisting essentially of a single-layer of a nonwoven fibrous thermal insulation comprising a fiber matrix of inorganic fibers, thermally insulative inorganic particles dispersed within the fiber matrix, and a binder dispersed within the fiber matrix so as to hold together the fiber matrix. An optional organic encapsulation layer may also be used to encapsulate the nonwoven fibrous thermal insulation.

  • Publication number: 20220393267
    Abstract: A three dimensional flame barrier is described herein. The three dimensional flame barrier comprises a flame resistant material, wherein the flame resistant barrier has a complex geometry that is defined by a height, width and length, wherein the height of the complex geometry is substantially greater than the thickness of the flame resistant material from which it is formed wherein the flame resistant material comprises inorganic fibers, inorganic particles and an inorganic binder. In some embodiments, the flame barrier article can further comprise a fire protection coating disposed on a first major surface of the flame barrier material.
