ELECTRODE ASSEMBLY AND SECONDARY BATTERY COMPRISING SAME

An electrode assembly is made by stacking and winding a first electrode, a separator, and a second electrode, in which the first electrode includes a current collector, and an electrode active material layer provided on the current collector, in which an edge portion of the current collector provided at one end of a winding axis of the electrode assembly includes a non-coated portion on which no electrode active material layer is provided, and in which a non-coated portion of the first electrode is bent one or more times in a direction from a winding center of an electrode assembly toward an outer periphery of the electrode assembly.
