摘要

Abstract

The integration of laser-assisted in-situ synthesis and successive ionic layer adsorption and reaction (SILAR) for the fabrication of supercapacitors on lightweight, flexible substrates is investigated. The focus was placed on the modification of laser-fabricated copper electrodes with zinc hexacyanoferrate (ZnHCF), a Prussian Blue analog known for its exceptional electrochemical properties. The electrochemical performance of the modified electrodes is characterized by cyclic voltammetry and charge-discharge tests, demonstrating the effectiveness of the ZnHCF modification in improving the charge transfer kinetics. The synthesized ZnHCF/Cu composite electrodes exhibit high specific capacitance of 182.3 mF/cm² at a current density of 1 mA/cm² and excellent cycling stability.
