摘要： A secondary battery having an electrode assembly in which a positive electrode, a separator, and a negative electrode are alternately stacked, and a can configured to accommodate the electrode assembly is provided. The negative electrode is disposed on an end of the electrode assembly in a direction of one side of the electrode assembly so that a negative electrode non-coating portion protrudes more than the separator with respect to a direction of a winding center axis of the electrode assembly. The positive electrode is disposed on an end of the electrode assembly in a direction of the other side of the electrode assembly so that a positive electrode non-coating portion protrudes more than the separator with respect to the direction of the winding center axis of the electrode assembly. The can includes a first can contacting the positive electrode and a second can contacting the negative electrode.
