Abstract

We demonstrate a simple and scalable strategy for synthesizing hierarchical porous NiCo₂O₄ nanowires which exhibit a high specific capacitance of 743 F g⁻¹ at 1 A g⁻¹ with excellent rate performance (78.6% capacity retention at 40 A g⁻¹) and cycling stability (only 6.2% loss after 3000 cycles).
