This study investigates the electrochemical properties of zinc hydroxide (Zn(OH)2) thin films synthesized through two distinct methods: chemical bath deposition (CBD) and successive ionic layer adsorption and reaction (SILAR). Notable variations in crystallite size, morphology, and bandgap energy were observed between the films synthesized using two methods. Specifically, a reduction in crystallite size was evident in films produced via the SILAR method, accompanied by an increase in bandgap energy. Morphological analysis revealed that CBD-deposited films exhibited a needle-like structure, while SILAR-synthesized films displayed a microflower-like texture. Electrochemical characterization in a 2 M KOH solution indicated that the Zn(OH)2 needles and microflowers thin film electrodes achieved remarkable specific capacitances of 329 F/g and 179 F/g at a current density of 1 A/g, respectively. Furthermore, both films demonstrated impressive cycling stability, retaining 78% and 74% of their original capacitance after 3,000 cycles at a scan rate of 100 mV/s. The findings of this study elucidate the significant impact of growth methods on the electrochemical properties of Zn(OH)2 thin films, providing valuable insights for the advancement of materials science and electrochemistry.
