基于过渡金属硫化物/还原氧化石墨烯复合物的高性能超级电容器
Transition Metal Sulfides Hybridized with Reduced Graphene Oxide for High-Performance Supercapacitors
摘要
Abstract
To assemble high-energy density asymmetric supercapacitors,the development of electrode mate-rials with large specific capacitances,negligible volume changes and long cycling stability is highly required. The hybrids of multiple transition metal sulfides with carbon nanomaterials are promising electrode materials . In this study,a hybrid consisting of Cu-Mo sulfides grown on microwave exfoliated reduced graphene oxide (CuS-MoS2/MErGO)was thus synthesized by means of a hydrothermal method. The CuS-MoS2/MErGO hybrid exhibits a specific capacitance up to 861.5 F/g at a current density of 2 A/g and long cycling life. An asymme-tric supercapacitor was assembled using the positive electrode of NiS/MErGO and the negative electrode of CuS-MoS2/MErGO. It delivers an energy density of up to 54.2 W·h·kg?1 at a power density of 1.28 kW/kg when a cell voltage of 1.6 V is applied. Therefore,the TMS hybrids are promising electrode materials for high-perfor?mance electrochemical energy storage applications such as for the assemble of asymmetric supercapacitors .关键词
