摘要：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).
