Abstract: A resin composition, a flame-resistant structure and a battery package are provided. The resin composition includes a resin, a crystalline hydrate, and urea, wherein the weight ratio of crystalline hydrate to resin to urea is 6:1.5-5:1.2-3. The flame-resistant structure includes a body. The body includes a cured resin composition. The resin composition includes a resin, a crystalline hydrate, and urea, wherein the weight ratio of crystalline hydrate to resin to urea is 6:1.5-5:1.2-3. The battery package includes a battery and the flame-resistant structure.

Abstract: A protective structure is provided, which includes a porous layer and a surface layer disposed on the porous layer. The porous layer includes a first copolymer, a plurality of pores, and a plurality of first silica particles, wherein the first copolymer is polymerized from a first monomer composition. The first monomer composition includes N,N-dimethylacrylamide and N-vinylpyrrolidone. The surface layer includes a second copolymer, a plurality of fibers, and a plurality of second silica particles, wherein the second copolymer is polymerized from a second monomer composition. The second monomer composition includes N,N-dimethylacrylamide and N-vinylpyrrolidone.
