Abstract:
Renewable energy storage systems are gaining interest due to the depletion of non renewable energy sources and environmental concerns, while wearable devices and hybrid
electric cars demand innovative storage solutions. However, supercapacitors are now
thought to be the most promising power source for a range of electronic devices. In this
work, NiCo2O4@SnS2 nanosheets were synthesized on carbon cloth by utilizing a simple
hydrothermal technique. The developed electrode material (NiCo2O4@SnS2 /CC) was
investigated for the supercapacitor applications. The high specific surface area, enhanced
kinetics, good synergy, and distinct architecture of NiCo2O4@SnS2 nanosheets produce a
large number of active sites with substantial energy storage potential. As a supercapacitor,
the electrode exhibits improved capacitance of 655.7 F/g at a current density of 2 A/g as
compared to NiCo2O4/CC (560 F/g). Moreover, the electrode achieves 95.3 % of its
preliminary capacitance after 10,000 cycles at 2A/g. Our results show that NiCo2O4@SnS2
/CC nanosheets could be attractive electrode material for the development of
supercapacitors
