Title:
FLAMEPROOF STRUCTURE, MANUFACTURING METHOD THEREFOR, AND BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2023/145883
Kind Code:
A1
Abstract:
The present invention provides a flameproof structure which, in addition to having more excellent heat insulating effect and flameproof effect, achieves enhanced joint strength between a battery case and a heat insulating material, has little time-dependent deterioration of the joint strength and excellent reliability, and further has excellent followability to the internal shape of the battery case. A flameproof structure (1) comprises a resin base material (20) and a heat insulating material (10) containing inorganic fibers or infusible fibers, and in a joint layer (30) obtained by joining the resin base material (20) and the heat insulating material (10), a formation material for the resin base material (20) enters space in a formation material for the heat insulating material (10) and is integrated. This flameproof structure (1) is obtained by using the heat insulating material (10) as an insert member and insert-molding the formation material for the resin base material (20). A battery module (100) is provided with a storage battery (110), and a battery case which houses the storage battery (110) and at least one of the canopy, sidewall, and bottom wall of which is the flameproof structure (1).
