In this study, nickel oxide (NiO) thin films are deposited on three‐dimensional nickel foam by a facile two‐step method for application in Li‐ion batteries (LIBs). These NiO films on Ni foam are tested as Li‐ion batteries anodes. The rough NiO thin film with the shortest deposition time (3 min) shows the best Li‐ion battery performance. A high specific capacity of 917 mAh g −1 is achieved at a charge–discharge current of 0.5 C and even after 100 cycles, a capacity of 838 mAh g −1 is still retained. The electrode also shows a good rate capability. This study shows that NiO electrode prepared with this method can be a promising candidate for LIBs anodes materials.
