Title:
HEAT INSULATING PROTECTIVE LAYER, BOX, BATTERY, AND ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/093459
Kind Code:
A1
Abstract:
The invention relates to the technical field of protective materials, and particularly to a heat insulating protective layer, a box, a battery, and an electrical apparatus. The heat insulating protective layer reduces the risk that the outer envelope of a battery pack becomes damaged by heat during a battery thermal runaway, and reduces the risk that heat leaks to the outside, generating an open flame, causing a fire. The invention comprises a first surface and a second surface disposed back to back, the first surface being used for facing a heat source entity, with an axial heat conduction coefficient T1 being smaller than a transverse heat conduction coefficient T2; when heat generated by the heat source entity is radiated to the first surface, and when the temperature of the first surface is less than or equal to 1600℃, i.e., when heat is radiated to the first surface, causing the temperature of the first surface to be within the range of less than or equal to 1600℃, the temperature of the second surface does not exceed 1200℃. When the heat source entity radiates a certain amount of heat, the heat insulating protective layer can effectively block the heat, controlling the temperature to be within a certain range, and reducing the risk that a structure disposed at the second surface is damaged by high temperatures.
