Abstract

The invention particularly relates to a preparation method of a carbon cloth in-situ growth hollow three-dimensional Co9S8 / NiCoMo oxyhydroxide core-shell electrode material. Hollow Co9S8 nanotubes arebeneficial to electrolyte permeation, cobalt sulfide has high conductivity, so that the structural stability of the material is improved. Epitaxially grown NiCoMo oxyhydroxide nanosheets have high specific capacitance, a formed hollow three-dimensional network structure provides channels and more active sites for electron and ion transmission and permeation, so that the electrochemical performance is improved. An electrochemical performance test result shows that the specific capacity of a single electrode reaches 6.2 F.cm<-2> when the current density is 3mA cm<-1>.

Description

technical field

[0001] The invention relates to the technical field of supercapacitor electrode materials, in particular to a carbon cloth in-situ grown hollow three-dimensional core-shell Co 9 S 8 / Ni-Co-Mo oxyhydroxide electrode material preparation method.

[0002] technical background

[0003] Supercapacitor is a new type of energy storage device whose performance is between that of batteries and traditional capacitors. It has the characteristics of high power density, fast charging and discharging, and long service life. It is one of the most promising green energy sources. , with the development of science and technology, traditional energy has long been unable to meet people's growing actual needs, and energy problems have become increasingly serious. Therefore, the development of new energy conversion devices and materials has become an urgent problem to be solved, and energy conversion technologies such as supercapacitors are becoming more and more New electrode ma...
