Evidence Details
The prepared solution was poured into a 100-mL hydrothermal synthesis reaction kettle followed by 50 min of intense stirring. The microwave hydrothermal reaction (XH-800S, Beijing Xianghu Co., Ltd, China) was carried out at a temperature of 120 ℃ for 30 min.
The asymmetric supercapacitor device using NiCo-LDH@TAC600-0 and TAC provided an energy density of 30.8 Wh kg−1 at 800 W kg−1 and a capacitance retention rate of 72.5% after 5000 cycles.
NiCo-LDH@TAC600-0 (without KOH activation) as an electrode material delivered a specific capacitance (Cs) of 1250 F g−1 at 1 A g−1 and 1035 F g−1 at 10 A g−1, with a rate performance of 82.8%.
