Template-free chemical growth on Ni foam and thermal treatment results in homogeneous FeCo 2 O 4 submicron-tube arrays which serve as binder-free electrodes with high capacitance, rate-capability and cycling-stability owing to FeCo 2 O 4 conductivity, high porosity, and strong bonding between tubes and Nifoam,allallowingevensymmetric devices to have superior energy density.
