Synthesis of Conductive Trypan Blue–Nickel MOF Nanosheet Array for an Asymmetric Supercapattery

Great efforts have been made to design and fabricate low-cost, high efficiency advanced electrode materials for energy storage devices such as batteries and high-performance supercapacitors. Choosing organic and redox active species that increase the Faradaic charge storage of electrode systems has thus become a challenge to increase energy density and conductivity. To this aim, herein, trypan (Try) blue–nickel metal–organic framework (Try–Ni-MOF) nanosheet array is fabricated via a hydrothermal method and used in an asymmetric supercapattery. The Try–Ni-MOF electrod exhibits a specific capacity of ۹۰۹.۹۸ F g−۱ at a current density of ۱ A g−۱ and a high energy density, which is due to the increase in its number of pores and surface created facilitate electrolyte contact for electrochemical reactions
