Title:
FLAMEPROOF MATERIAL, METHOD FOR PRODUCING SAME, AND BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2023/182385
Kind Code:
A1
Abstract:
Provided are: a flameproof material that is configured as a multilayer structure, thus has an excellent heat insulation effect and flameproofing effect, and additionally has excellent reliability in which the layering state of each layer is suitably maintained without using an adhesive; a method for producing the flameproof material; and a battery module. The flameproof material (1) includes a heat insulation material (10) containing inorganic fibers or infusible fibers, and an inorganic fiber cloth (20). The heat insulation material (10) and the inorganic fiber cloth (20) are integrated by a physical means that is preferably at least one of needling, resin stapling, and sewing. In addition, storage batteries (110) are accommodated in a battery case (120) in the battery module (100), and the flameproof material (1) is disposed in at least one of the lid, the side walls, and the bottom wall of the battery case (120) and/or the area between the storage batteries (110).
