Porous layered stacked MnCo2O4 cubes with enhanced electrochemical capacitive performance

Author affiliations

Abstract

The development of new electrode materials with various components, structures, morphologies and porosities is critical for improving the performance of supercapacitors. Here, we report a facile strategy for synthesizing porous layered stacked MnCo2O4 cubes through a hydrothermal method, followed by annealing treatment. Compared with other morphologies of MnCo2O4, the specific capacitance of porous layered stacked MnCo2O4 cubes reaches 480.5 F g−1 at a current density of 1 A g−1. Furthermore, porous layered stacked MnCo2O4 cubes show an ultrahigh capacity retention of 75.7% even at a current density of 25 A g−1 and good cycling stability with 96.6% specific capacitance retained after 3000 cycles, which makes porous layered stacked MnCo2O4 cubes a great potential electrode material for supercapacitor applications.
