The present invention relates to a case having a thermal barrier layer for a single cell. The composite case comprises a substrate and a double-layer structure coating on the substrate, wherein the double-layer structure coating includes an inner layer containing an aerogel material which has a ultra-low thermal conductivity, and an outer layer containing a barrier material which may prevent an electrolyte solvent from permeating into the inner layer. According to the present invention, the composite case can preserve cases in a prismatic or pouch cell from melting when cell goes to thermal runaway.
