The MnO2 nanoparticles decorated CoPBA nanocubes with excellent electrochemical performance were assembled via a simple precipitation method. The composites provide the following synergistic benefits: CoPBA allows the easy dispersion of MnO2 nanoparticles that act as the conductive building block with high specific capacitance to improve its conductivity and capacitance. Consequently, CoPBA-8MO delivers commendable specific capacitance of 945F g−1 at 1 A g−1, overwhelming pure CoPBA, MnO2 and

A composite supercapacitor electrode material, MnO2 decorated cobalt-iron Prussian blue analogue (CoPBA), has been rationally designed and fabricated through a facile precipitation method. The surface encapsulation of MnO2 onto CoPBA can result in improved electrochemical performances, because the uniformly covered MnO2 increases not only the electrical conductivity for faster ion transport but also the specific capacitance by providing more active sites. A maximum specific capacitance of 945F g(-1) at 1 A/g is observed for CoPBA@MnO2, which is 3.2-fold and 6.7-fold of those of pure CoPBA and ...
