Kind Code:
A1
Abstract:
A positive electrode current collector for a lithium secondary battery according to the embodiments of the present invention may comprise: a first metal layer including a first region, and a second region thinner than the first region; and a second metal layer disposed on the second region of the first metal layer, and having a composition different from that of the first metal layer. Accordingly, generation of heat due to differences in resistance around the coupling area can be prevented when a positive electrode current collector couples with a positive electrode tab and the like.
