Sumario:VO(2)/TiO(2) nanosponges with easily tailored nanoarchitectures and composition were synthesized by electrostatic spray deposition as binder-free electrodes for supercapacitors. Benefiting from the unique interconnected pore network of the VO(2)/TiO(2) electrodes and the synergistic effect of high-capacity VO(2) and stable TiO(2), the as-formed binder-free VO(2)/TiO(2) electrode exhibits a high capacity of 86.2 mF cm(−2) (~548 F g(−1)) and satisfactory cyclability with 84.3% retention after 1000 cycles. This work offers an effective and facile strategy for fabricating additive-free composites as high-performance electrodes for supercapacitors.
