In order to improve the electrochemical performance of layered double hydroxide (LDH) and its application in flexible supercapacitors, MnMoO4 and Nickel-Manganese layered hydroxides (NiMn-LDH) nanosheets were grown on the surface of carbon cloth (CC) by stepwise hydrothermal method, and the NiMn-LDH/MnMoO4/CC composite electrode with nanoarray microstructure was obtained. NiMn-LDH/MnMoO4/CC//AC/CC flexible supercapacitors were assembled by exploiting the flexible electrode and AC/CC as positive and negative electrode materials respectively. The test results of three electrodes show thal the specific capacitance for the electrode is 2 304,5 F ⋅ g-1 at 1 A ⋅ g-1 current density. and the ratio of the flexible electrode attains 78.2% at a current density of 20 A ⋅ g-1. The device presents the maximum energy density of 20.5 Wh ⋅ kg-1, and the maximum power density of 4 804.1 W ⋅ kg-1. After 10000 cycles, the specific capacitance retention rate holds 96.6%. In addition, the specific capacitance of the twisted electrode of the flexible device can still maintain 96.0% of the normal state, showing good flexibility and electrochemical performance.
