simple synthesis of fe3o4@fe3s4 nanocomposites coated with polyindole-polythiophene for high-performance supercapacitor

To prevent a major energy crisis in the near future, it is necessary to assemble efficient electrochemical energy storage devices such as supercapacitors. herein, a fe3 o4 @fe3 s4 nanocomposites coated with polyindole-polythiophene on nickel foam (nf) has been prepared by following a low facile, multistep method. in terms of structural and electrochemical performance, the nanocomposites have been investigated. the electrochemical properties of as fabricated fe3 o4 @fe3 s4 @pin-pth are studied in 2m koh. a specific capacitance of 100.83 f g^−1 at a current density of 2 a g^-1. the results of the synthesized sample in comparison with fe3 o4 show that using sulfide metal and polymer component improve the electrochemical performance. these characteristics of fe3 o4 @fe3 s4 @ pin-pth as the active material illustrate a sutiable performance as a cathode material for electrochemical energy storage.
