Titanium-doped Binary Strontium-Copper Oxide as a High-Performance Electrochemical Pseudocapacitive Electrode Material |
| 초록 |
Ti-doped SrCu2O2 (TSCO) is prepared using solid-state chemical reaction to apply as electrochemical pseudocapacitors. Crystallographic, Spectroscopic, and Morphological study of prepared TSCO confirmed the crystallinity. TSCO demonstrate specific capacity (Cs) of ca. 1167.6 and 661.8 F/g at a scan rate of 5 mVs-1 and 0.02 A/g applied current density, respectively. The increment of specific capacity value can be explained by the insertion of Ti as dopped material in the SCO which is simultaneously intensify the rate of ion intercalation/de-intercalation during charging/discharging (CD). Even the cycling stability of TSCO was found excellent with only 4.4% decrease after 10000 CD cycling. |
