Hydrothermal Synthesis of Flower-Like NiCo2-LDH/MXene-Ti3C2 Composites for High-Performance Capacitors

In this work, NiCo2-LDH/Ti3C2 composites have been grown directly on Ni foam using a one-step hydrothermal synthesis method. The combination of NiCo2-LDH nanosheets and MXene (Ti3C2) shows cooperative effect for supercapacitors with expressively enhanced electrochemical performances. The NiCo2-LDH/Ti3C2 electrode shows a relatively high areal capacity of 4.39 C cm−2 at 5 mA cm−2, even at 20 mA cm−2; the areal capacity retention is 77.5
