ELECTRODE ASSEMBLY AND SECONDARY BATTERY COMPRISING THE SAME

An electrode assembly and a secondary battery including the same are provided. The electrode assembly includes an electrode stack, in which electrodes and a separator are alternately stacked to be wound, and a temperature difference compensating member disposed at a winding center of the electrode stack such that a temperature difference between a winding outer shell and a winding center of the electrode stack is reduced. The temperature difference compensating member includes a phase change material.
