Abstract
A secondary battery and a method of manufacturing the same are disclosed. In one aspect, the method includes preparing an electrode assembly comprising a positive electrode plate, a negative electrode plate, and a separator interposed therebetween. The method also includes freezing the electrode assembly after the electrode assembly is filled with an electrolyte solution, dipping the frozen electrode assembly in a liquid polymer material, retrieving the dipped electrode assembly from the liquid polymer material, and curing an external surface of the electrode assembly.
