Summary: Rationally designed and constructed self-supporting electrodes with high energy exporting densities can potentially lead to wearable and portable devices in the future. A hydrothermal method with a chelating agent was used to grow Co3S4-Ni3S2 on nickel foam for high-performance supercapacitors, demonstrating excellent specific capacitance and rate capability. The assembled all-solid-state asymmetric supercapacitor showed impressive energy density and power density, along with exceptional durability, making it one of the top performers in similar reports.

Summary: In this study, Co-doped Ni3S2 supported on Ti3C2/Ni foam (Co-Ni3S2/Ti3C2/NF) composites were prepared using a hydrothermal method. The composites exhibited a three-dimensional network structure and showed excellent electrochemical performance, with a specific capacitance of 1457 F g(-1) at 1 A g(-1) and 127.35% of the initial specific capacity after 5000 cycles at 10 A g(-1). The asymmetric supercapacitor using Co-Ni3S2/Ti3C2/NF as the positive electrode and activated carbon as the negative electrode achieved an energy density of 30.4 Wh kg(-1) at a power energy density of 0.8 kW kg(-1). This work provides a useful method for the design of supercapacitor electrodes with excellent electrochemical performance coated with MXenes.
