ELECTRODE ASSEMBLY

An electrode assembly, in which a positive electrode, a separator, a negative electrode are wound in a state of being provided. The positive electrode includes a first positive electrode and a second positive electrode, each of which is manufactured by applying a positive electrode active material on a surface of a positive electrode collector, and the positive electrode active material is not applied on one end of the current collector to form a positive electrode non-coating portion on which the positive electrode collector is exposed, and the positive electrode non-coating portions of the first positive electrode and the second positive electrode are bonded to be connected to each other. An electrode assembly is provided where the negative electrode includes a first negative electrode and a second negative electrode.
