[0002] The high-temperature resistant fire and heat insulation pad disclosed in the publication number CN210134051 U includes a first fiberglass layer, a metal layer, a fire and heat insulation pad and a second fiberglass layer. The metal layer is located between the first fiberglass layer and the fire and heat insulation pad. The metal layer is closer to the fire source side relative to the fire and heat insulation pad. A second fiberglass layer is provided on the side of the fire and heat insulation pad opposite to the metal layer. One surface of the first fiberglass layer and the metal layer is adhered through a first adhesive layer, and one surface of the metal layer and the fire and heat insulation pad is adhered through a second adhesive layer.

[0003] When a lithium battery catches fire and explodes, it can effectively reduce the impact force generated by the high-temperature and high-pressure gas inside the battery compartment, play a buffering role, prevent the high-temperature and high-pressure gas from breaking through the fire and heat insulation pad, and play a role in protecting the fire and heat insulation pad. At the same time, the metal layer can withstand high temperatures and play a role in fire prevention and high-temperature resistance during use.

[0004] However, as a heat insulation pad inside the battery, it lacks a certain insulation structure inside, resulting in poor insulation effect. Moreover, the presence of the metal layer will affect the use of the battery and increase the risk of conduction. At the same time, the inside of the heat insulation pad lacks a certain hard layer, thereby reducing the buffering effect, and the protection degree of this solution for battery heat insulation is not high.

Mica materials have good high-temperature resistance and are not easily deformed, expanded, or softened at high temperatures, further improving the high-temperature resistance and heat insulation performance. At the same time, the non-deformable characteristic of mica brings a certain hard buffering to the heat insulation pad, and the insulating characteristic of mica can prevent the battery from conducting electricity, thus better improving the protection of the battery heat insulation pad.
