A simple continuous hydrothermal method was used to synthesize a NiFe2O4@Ni-Mn LDH/NF composite. The layered structure provides large void transfer the electron effectively, and composite materials exhibit remarkable electrochemical performance including excellent specific capacitance (1265 F g-1 at 1 g-1) cycling stability (the remains 80.9% after 5000 cycles). In addition, asymmetric supercapacitor exhibits high energy density of 96.2 W h kg-1 power 700 kg-1, there is an extraordinarily good with capacity retention rate 92.5% 4000 cycles. outcomes indicate that electrode has potential application as high-performance supercapacitor.
