The present invention relates to a negative electrode current collector for a zinc-ion battery, a method for manufacturing the same, and a zinc-ion battery comprising the same. More specifically, the negative electrode current collector for a zinc-ion battery of the present invention can prevent side reactions such as hydrogen evolution reaction, corrosion, and dendritic growth of zinc by forming a carbon nanotube derivative-based protective film layer on the negative electrode current collector substrate, and can remarkably improve the electrochemical stability and interfacial stability between the electrode and the electrolyte. In addition, a thin and uniform protective film layer can be formed with a simple manufacturing process, and large-area application is possible. Furthermore, by applying the negative electrode current collector for a zinc-ion battery to a zinc-ion battery, there is an advantage of achieving excellent charge/discharge efficiency, long lifespan, and fast charging capability.
