Synthesis of novel CoS2 nanodendrites with high performance supercapacitors

Abstract

Cobalt disulfide (CoS2) nanodendrites were synthesized via a one-step solvothermal approach with high yield, the obtained nanoparticles present uniform size and 3D morphology assembled by nanosheets. The as-prepared CoS2 nanodendrites deliver relatively high specific capacitance of 311.06 F g-1 at 1 A g-1 and good cycle stability, notably, CoS2 nanodendrites exhibt excellent cycling durability after 3000 cycles with a total capacitance loss of about 19.78 % (80.22 %) at 4 A g-1.
