Abstract:
A battery casing including a container configured to house an electrode assembly, wherein the container includes a bottom wall and a plurality of side walls, the bottom wall and the plurality of side walls are integrated to define an open side opposite to the bottom wall and to define a space for housing the electrode assembly, at least one of the bottom wall and plurality of the side walls includes a composite including a thermotropic liquid crystal polymer and a nanoclay dispersed in the thermotropic liquid crystal polymer, wherein the main chain of the thermotropic liquid crystal polymer includes an aromatic oxycarbonyl repeating unit and an alkylene moiety-containing repeating unit, and at least a portion of the nanoclay is present in an exfoliated state, and an X-ray diffraction pattern of the composite does not exhibit an intrinsic peak corresponding to the nanoclay.
Abstract:
A battery casing including a container configured to house an electrode assembly, wherein the container includes a bottom wall and a plurality of side walls configured to define an open side opposite to the bottom wall and to define a space for housing the electrode assembly, at least one of the bottom wall and the plurality of side walls includes a composition including a base polymer and a plurality of nucleating agent particles dispersed in the base polymer, the base polymer includes a polyethylene polymer, the nucleating agent particles have a rod shape, the aspect ratio of the nucleating agent particles is greater than or equal to about 2, and an amount of the nucleating agent particles is about 0.01 parts by weight to about 3 parts by weight, based on 100 parts by weight of the base polymer.
Abstract:
An eco-friendly fire-retardant polymer composition, a molded article made from the composition, and a method of manufacturing the molded article. The composition includes: a thermoplastic resin containing polycarbonate; a bio-based resin containing polytrimethylene terephthalate extracted from a biomaterial; and an impact modifier containing a core-shell type elastomer.
