Abstract
Porous multi component Nickel Cobalt Manganese Sulfide (NCMS) nanosheets have been grown on Ni
foam by cathodic electrodeposition method. The as-prepared NCMS nanosheets sample is used as an
electrode material for supercapacitor application due to its large electrochemically active surface and
high porosity structure. Moreover, NCMS nanosheets have good electrical and mechanical connections to
the conductive Ni foam to achieve enhanced reaction kinetics with improved electrode integrity. The
NCMS nanosheets exhibit an ultrahigh specific capacitance of 2717 F/g at a current density of 1 A/g with
excellent cyclic stability and energy density of 94.07 Wh/kg. The electrodeposited NCMS nanosheets with
extraordinary electrochemical performance enable the novel electrodes to hold great potential for high
efficient energy storage systems.
