Has broad application prospects and huge economic value. Electrode materials is a key factor in determining the performance of supercapacitors, which has been a research focus. This experiment using electrodeposition method, ruthenium chloride solution as the base material for preparing titanium plate electrode material, the main component of amorphous ruthenium dioxide. Testing and characterization of the preparation process using segmented ladder method, constant current deposition, annealing ultimately to prepare amorphous ruthenium dioxide electrode, and its cyclic voltammetry, constant current charge and discharge, scanning electron microscopy in order to understand the parameters affecting the preparation process, improve their specific capacitance and stable performance.
