Direct growth of Mn(OH)2/Co(OH)2 nanocomposite on carbon cloth for flexible supercapacitor electrodes

The present work reports, direct growth of binary metal hydroxide ((Mn(OH)(2))/(Co(OH)(2))) nanocomposite on flexible carbon cloth substrate by a simple and affordable chemical bath deposition method. The as-prepared binder free binary metal hydroxide nanocomposite electrode exhibits a specific capacitance as high as 385 F g(-1), in the symmetric two-electrode configuration in a stable potential window ranging from OV to IV. At a specific power of 1 kW kg(-1) , the supercapacitor gives a specific energy of 27 W h kg(-1) . The device exhibits a cycling stability of 96% even after 6000 cycles of charge-discharge at a current density of 2 A g(-1) . The structural and morphological analyses of the electrodes after the stability measurements, further confirm the superior electrochemical stability of the binary nanocomposite electrode. The results demonstrate the potential of Mn (OH)(2) /Co(OH)(2) nanocomposite for energy storage applications.
