Abstract: A battery cell stack of the present invention includes a plurality of battery cells and a resin layer wholly or partially in contact with an outer surface of at least one of the plurality of battery cells, wherein the resin layer includes a solvent-free adhesive and a flame retardant, and has a peel strength of 1,000 gf/in to 3,000 gf/in measured according to ASTM D3330, and a shear strength of 20 kgf/sq-in to 100 kgf/sq-in measured according to ASTM D1002, and the flame retardant includes one or more of a phosphorus-based flame retardant and a nitrogen-based flame retardant, such that the operational stability and flame retardancy may be simultaneously improved, while simplifying materials and processes necessary to manufacture the battery cell stack.

Abstract: A wireless communication terminal and a battery pack for the same are disclosed. The wireless communication terminal includes a battery pack having one or more battery cells supplying power to the terminal, wherein the battery pack includes a protective circuit senses an high temperature or pressure condition of the one or more battery cells and disconnects battery power from the terminal circuitry.
