Abstract
An electrode assembly for a secondary battery includes at least one positive electrode and at least one negative electrode alternately stacked in a state in which a separator is interposed therebetween. The positive electrode includes a first positive electrode having a single positive electrode tab and a second positive electrode having two or more positive electrode tabs. The negative electrode includes a first negative electrode having a single negative electrode tab and a second negative electrode having two or more negative electrode tabs. The output of the electrode assembly is adjustable.
