摘要

The present invention relates to a method for preparing a NiCo 2 S 4 / Ni (OH) 2 center-shell nanosheet array having a hierarchical mesopore structure on a three-dimensional conductive carbon electrode, 2 S 4 / Ni (OH) 2 center-shell nanosheets are directly grown to form electrodes with many pore layers to reduce the transport path of electrolyte ions during the super capacitor charging / discharging process, It is possible to facilitate the access to the vehicle. Further, the three-dimensional conductive layered mesoporous structures on carbon cloth electrode NiCo 2 S 4 / Ni (OH ) 2 core-shell nano-sheet array electrode at a current density of 20 mA / cm 2 by applying the super-capacitor 209 mA h / cm 2 , and the storage capacity after 2000 cycles is reduced by only 5.5%, which indicates excellent long-term cyclic stability.
