Fabrication of Flexible Nickel Hydroxide Electrode for Nickel–Zinc Battery
https://doi.org/10.1007/s11814-025-00575-1
Abstract
Nickel–Zinc (Ni–Zn) batteries are attractive as a potential alternative to conventional lithium-ion batteries due to their costeffectiveness
and environmental benefits. This study explores the fabrication of a flexible electrode using nickel hydroxide
(Ni(OH)2) that is electrochemically deposited on a Buckypaper and polydimethylsiloxane (BP@PDMS) substrate. The electrodeposition
condition is optimized by varying applied current density (− 1, − 1.5, and − 2 mA/cm2), and − 1.5 mA/cm2 condition
yields the highest specific capacity of 0.2 mAh/cm2. According to spectroscopic and optical analyses, when − 1.5 mA/
cm2 is applied, Ni(OH)2 is properly deposited on the BP@PDMS electrode, inducing a high specific capacity. Furthermore,
Ni(OH)2/BP@PDMS cathode is compared with (i) Ni foil cathode, and (ii) untreated BP@PDMS cathode to demonstrate
its superior redox reaction, capacity, and stability. Despite minor capacity decay of Ni–Zn battery occurring for a long cycle
test, the findings suggest that Ni–Zn batteries are suitable for portable electronic devices and offer a promising alternative
to existing battery technologies.
