Zusammenfassung:	Provided is a secondary battery with improved safety through filling a polymer in a hardened state, and a method of manufacturing the same. The method of manufacturing a secondary battery according to the present disclosure includes preparing a polymer slurry by adding a polymer particle to an electrolyte solution, injecting the polymer slurry to a battery casing in which an electrode assembly is received, changing the polymer slurry to a polymer solution by heating the battery casing, and hardening the polymer solution by cooling the battery casing.
