摘要: A cost-effective and uniform crystal with different structures was fabricated using a facile chemical bath deposition technique for electrochemical supercapacitor (SC) applications. In this study, CuS, PbS, CuS@PbS composite electrodes were SCs. The morphology structure of the analyzed by field emission–scanning electron microscopy, transmission X-ray diffraction, photoelectron spectroscopy. electrode delivered outstanding performance in SCs high specific capacitance 1004.42 F g −1 at current density 2.85 , good cycling stability (only 2.9% loss after 3000 cycles ), higher energy 33.89 Wh kg power 714.28 W an excellent rate capability compared to other electrodes. These results show that can be used improve surface is promising positive material SC
