Abstract
The present application relates to a method and an apparatus for manufacturing an electrode assembly of a secondary battery. Embodiments of the present application propose a method for manufacturing an electrode assembly of a secondary battery, the method comprising joining a positive electrode plate and a first separator to form a positive electrode composite plate body; joining a negative electrode plate and a second separator to form a negative electrode composite plate body; winding the positive electrode composite plate body and the negative electrode composite plate body together to form an electrode assembly, wherein the positive electrode plate and the negative electrode plate are disposed to isolate from each other by the first separator and the second separator.
