Abstract

En 中文

• NiCoAl-LDH/MXene/CNT was synthesized by using simple hydrothermal method. • NiCoAl-LDH/MXene/CNT electrode shows capacitance of 984.8 F g−1 at 0.5 A g−1. • NiCoAl-LDH/MXene/CNT//AC device achieves 44 Wh kg−1 energy density & 749.2 W kg−1 power density. • NiCoAl-LDH/MXene/CNT//AC ASC device retains 76.4% capacity after 10,000 cycles. • Density of states was measured for NiCoAl LDH/MXene/graphene composition.
