2D/2D nanostructures based on NiCo2O4/graphene composite for high-performance battery-type supercapacitor

Recent advances in Ni-materials/carbon nanocomposites for supercapacitor electrodes

“…Recently, several kinds of research have been reported on supercapacitors based on NiCo 2 O 4 /carbon nanomaterials. [44][45][46][47][48] Ni(OH) 2 -based supercapacitors are widely used due to efficient charge storage and are environmentally friendly. In supercapacitors based on Ni(OH) 2 /carbon nanomaterials, the performance characteristics are improved.…”

Synthesis of Co3O4/NiCo2O4 Double‐Shelled Nanocages with Enhanced Capacitive and Oxygen Evolution Reaction Properties in Battery‐Supercapacitor Hybrid Devices

“…As for NiCo 2 O 4 , its specific capacity is not as good as Co 3 O 4 , but it is more stable under cycling test. Therefore, these two oxides combine together to gain much better electrochemical properties and good electrocatalytic OER performance [34–37] …”

“…Therefore, these two oxides combine together to gain much better electrochemical properties and good electrocatalytic OER performance. [34][35][36][37] In this study, we first synthesized ZIF-67 nanomaterials at 25 °C. (12.03 W h kg À 1 ) and great stability with a capacitance retention (85.39 %, 10000 cycles).…”
