The goal of this research was to create a high electro-catalytic electrode material for supercapacitor devices. In this work, WS₂ incorporated NiFe nanocubes were designed as an efficient electrode material for Supercapacitor application using the Kirkendall effect under probe sonication techniques. In Supercapacitors, WS₂ incorporated NiFe nanocubes electrode demonstrated a specific capacitance performance of 671 F/g and a capacitance retention of 90% over 5000 cycles at a current density of 1 A/g. The assembled WS₂ incorporated NiFe//AC asymmetric supercapacitor device achieved an energy density of 55 Wh/kg and a power density of 1012 W/kg at 1 A/g current density. The constructed WS₂ incorporated NiFe //AC device showed capacitance retention and coulombic efficiency of 83% and 98%, respectively, in stability tests after 6000 cycles. These impressive results indicate that the WS₂ incorporated NiFe electrode is a promising material for Supercapacitors, which could lead to significant advancements in high-tech electronic devices.
