In this study, a hydrothermal method was used to synthesize nickel hydroxide (Ni(OH)2) powders, which are active materials for use in (Ni) electrodes located nickel-zinc (NiZn) batteries. X-ray diffraction (XRD), scanning electron microscopy (SEM), zeta potential, Brunauer-Emmett-Teller (BET), and electrochemical characterization were characterize the cathode material prepared Ni electrodes. These results showed β-phase Ni(OH)2 nanosphere with well-crystalline structure. The test indicated electrode has stable cyclic cycle half-cell. Based on performance results, Ni(OH)2, synthesized at 70oC 3h of aging time (Ni_pH 12_3h_70oC), best-performing metal oxide. Compared electrodes, NiCoZn exhibited high OER (oxygen evolution reaction) ORR reduction activities because combination cobalt zinc oxides provides excellent electrolyte access capability promotes effective ion transfer through material. NiZn battery capacity 192.7 mAh gactive−1 10 mA cm−2 cycling durability (after 70 cycles). Benefiting from interaction between Ni, Co, Zn, onset potential current density, suggesting that is promising candidate as high-performance configuration Ni-based
