Electrochemical properties of Ni(OH)2/MnO2 on hybrid N-doped carbon structure as high-performance electrode material
Source abstract
Abstract
A hierarchical hybrid architectures are very crucial through assembly of various carbon-based materials such as graphene and carbon nanotubes to achieve high-performance supercapacitors for energy storage. In this study, we propose a new pyrolysis method to prepare nitrogen-doped hybrid carbon structure (N-HCS). Then, the binary metal hydroxides Ni(OH)2/oxide MnO2 deposited on N-HCS with multifunctionality between them, exhibits an excellent specific capacitance as high as1563F/g at 1A/g in 1mol/L Na2SO4 solution and stable cycling performance remaining 80% of the initial specific capacitance after 1000 cycles at current density of 10A/g. This work paves a pathway to prepare electrode materials of N-doped carbon structure/Ni(OH)2/MnO2 with high performance for applying in energy storage and conversion.
