The present disclosure provides a high-temperature nano-composite coating and a preparation method thereof, and a small bag flexible packaging coating. The high-temperature nano-composite coating provided by the present disclosure controls the fiber length. Moreover, high-temperature reinforcing filler and high-temperature expansion filler are introduced, to make the coating have ultra-high strength at high temperature without cracks caused by shrinkage at high-temperature. In addition, nanopowder, high-temperature skeleton filler and other additives are introduced to make the coating be uniform and stable and reach a slurry state similar to toothpaste. There is no precipitation and stratification during the placement process. Small packaging can be realized to facilitate construction and operation. Besides, the coating has a good bonding to furnace lining, and will not fall off from the furnace lining, thereby prolonging the service life of the furnace lining.

Provided are a heat transfer suppression sheet having an excellent heat transfer prevention effect and excellent retainability of inorganic particles and shape retainability at a high temperature, and a battery pack in which the heat transfer suppression sheet is interposed between battery cells. The heat transfer suppression sheet (10) includes inorganic particles (20), first inorganic fibers (30), and second inorganic fibers (31). The first inorganic fibers (30) are amorphous fibers. The second inorganic fibers (31) contain at least one kind selected from amorphous fibers having a glass transition point higher than that of the first inorganic fibers (30) and crystalline fibers.
