چکیده انگلیسی
The impressive electrochemical energy storage performance of Earth-abundant ternary copper cobalt sulfide (CCS) thin film electrodes that are prepared on stainless steel substrates via a simple and cost-effective hydrothermal process is demonstrated. The optimized CCS electrode shows a high specific capacitance of â¼516Â F/g at a current density of 10 A/g, a good rate capability of â¼72% at a high current density of 50 A/g, and a good cycling retention of â¼66% with a coulombic efficiency of â¼99% after 10,000 charge-discharge cycles. The CCS electrode exhibits a high energy density of â¼35.2Â Wh/kg at a power density of â¼6.6Â kW/kg. The excellent electrochemical supercapacitor properties of the CCS electrode are a result of a synergetic effect between the uniform full coverage, robust adhesion, and desired chemical composition. A low charge transfer resistance, resulting from the large electrochemically active surface area (ECSA) and good diffusion, significantly contributes to the enhanced electrochemical supercapacitor performance. This excellent CCS electrode material has the potential to become a low-cost and long-cycle life electrode for the next-generation high-power-capacity supercapacitors.
