Reduced graphene oxide anchored MnCo2S4 for solid state asymmetric capacitor device
A wide working potential range of asymmetric capacitor devices with solid state gel electrolytes have enormous advantages of energy storage devices like high capacity, long life and high-power density. Here, the sandwiched type rGO@MnCo2S4//rGO asymmetric supercapacitor (ASC) electrode was construct...

| description | A wide working potential range of asymmetric capacitor devices with solid state gel electrolytes have enormous advantages of energy storage devices like high capacity, long life and high-power density. Here, the sandwiched type rGO@MnCo2S4//rGO asymmetric supercapacitor (ASC) electrode was constructed and functioned with a wide potential of 1.6 V. The electrochemical evaluation was verified through a three-electrode operating system, it shows the MnCo2S4 and rGO@MnCo2S4 electrodes have 42.72 mAh g-1 and 82.57 mAh g-1 capacity values. Moreover, the constructed rGO@MnCo2S4//rGO ASC device shows a higher capacity of 140.83 mAh g-1 at 1 A g-1. In addition, the rGO@MnCo2S4//rGO ASC device also delivers a higher energy density of 37.55 Wh kg-1 and power density of 800 W kg-1. However, the stability of the rGO@MnCo2S4//rGO ASC device shows about 93 % cyclic retention after 3000 cycles. These results may show the rGO@MnCo2S4 electrode is an opted electrode material for supercapacitor applications. |
