The intelligent design of advanced anode materials plays a pivotal role in energy storage for lithium-ion (LIBs) and sodium-ion batteries (SIBs), and offering potential for broadening their practical applications through the development of flexible electrodes. In this study, Nickel hydroxide nanoflowers grown on Ni foam (Ni(OH)₂ NFs/NF) was synthesized by hydrothermal method. Subsequently nickel hydroxide nanoflowers-polyaniline (Ni(OH)₂ NFs/PANI) was synthesized by electrodeposition method. Ni(OH)₂ NFs/NF and Ni(OH)₂ NFs/PANI can be straightforwardly utilized as pliable electrodes. For the first discharge capacity, Ni(OH)₂ NFs/PANI electrode delivers higher capacity (1608.1 mAh g⁻¹) than Ni(OH)₂ NFs/NF (1464.1 mAh g⁻¹) for LIBs. For the first discharge capacity, Ni(OH)₂ NFs/PANI electrode delivers more superior capacity (473.4 mAh g⁻¹) than Ni(OH)₂ NFs/NF (406.6 mAh g⁻¹) for SIBs. Ni(OH)₂ NFs/PANI electrode demonstrated enhanced rate performance and cycling stability in comparison to Ni(OH)₂ NFs/NF electrode.
