摘要：VO₂/TiO₂ 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 VO₂/TiO₂ electrodes and the synergistic effect of high-capacity VO₂ and stable TiO₂, the as-formed binder-free VO₂/TiO₂ 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.
