Flower-like MoS_2 onto nitrogen-doped 3D graphene composite with active material for supercapacitor electrodes

摘要

MoS2 and graphene composites are promising materials for high-performance supercapacitors. Here, we prepared a novel flower-like MoS2 nanosheet/N-doped 3D graphene (MoS2/N-3DG) by hydrothermal method. Electrochemical characterizations indicate that the specific capacitance of MoS2/N-3DG can reach up to 301.2 F/g at 0.2 A/g and preserve 82% of the initial capacitance after 1000 cycles at 1 A/g. This result shows that MoS2/N-3DG can be applied in supercapacitors. (C) 2019 Elsevier B.V. All rights reserved.
