Facile synthesis of a two-dimensional layered Ni-MOF electrode material for high performance supercapacitors.

ABSTRACT: Recently, various metal-organic framework (MOF)-based supercapacitors (SCs) have received much attention due to their porosity and well-defined structures. Yet poor conductivity and low capacitance in most MOF-based devices limit their wide application. As an electrode material, 2D MOFs exhibit a rapid electron transfer rate and high specific surface area due to their unique structures. In this work, a 2D layered Ni-MOF is synthesized through a simple solvothermal method and serves as an electrode material for SCs. Electrochemical studies show that the Ni-MOF exhibits low charge transfer resistance, excellent specific capacitance of 1668.7 F g^-1 at 2 A g^-1 and capacitance retention of 90.3% after 5000 cycles at 5 A g^-1. Moreover, Ni-MOF//AC asymmetric SCs a
