Sumario:In this work, Co(OH)F nanorods@K(x)MnO(2) nanosheet core–shell nanostructure was assembled on Ni foam by a facile hydrothermal method and incorporated with an electrodeposition process. Benefiting from their core–shell nanostructure and heterogeneous nanocomposites, the arrays present high areal capacitance up to 1046 mF cm(−2) at 1 mA cm(−2) and display a remarkable specific capacitance retention of 118% after 3000 cycles. When the current density increases to 10 mA cm(−2), the capacitance is 821 mF cm(−2) displaying a good rate capability. The excellent electrochemical properties allow them to be used as a promising electrode material for pseudocapacitors and display wide application potential in the field of electrochemical capacitors.
