Ternary Nanohybrid of Ni₃S₂/CoMoS₄/MnO₂ on Nickel Foam for Aqueous and Solid-State High-Performance Supercapacitors.

ABSTRACT: To overcome the issues related to supercapacitor (SC) electrodes, such as high cost, low specific capacitance (C_s), low energy density (ED), requirements for expensive binder, etc., binderless electrodes are highly desirable. Here, a new ternary nanohybrid is presented as a binder-free SC electrode based on Ni₃S₂, CoMoS₄, and MnO₂. A facile two-step hydrothermal route, followed by a short thermal annealing process, is developed to grow amorphous polyhedral structured CoMoS₄ and further wrap MnO₂ nanowires on Ni foam. This rationally designed binder-free electrode exhibited the highest C_s of 2021 F g^-1 (specific capacity of 883.8 C g^-1 or 245.5 mAh g^-1) at a
