Abstract:
A negative electrode current collector for a lithium metal battery, including copper and having a sum of S(110) and S(100) of 50% or more, wherein the S(110) is a ratio of a region occupied by a (110) surface of copper based on an entire region occupied by copper at a surface of the negative electrode current collector, and the S(100) is a ratio of a region occupied by a (100) surface of copper based on an entire region occupied by copper at a surface of the negative electrode current collector.
