摘要:
Supercapacitor with high energy density and super-long cyclic durability is attractive for the rechargeable energy storage devices. The combination of multiple pseudo-capacitive materials is favorable for improving the energy density of supercapacitor, but the rationally designed electrode structures are highly desirable for achieving the super-long cyclic durability. Here we realize a novel hierarchical NiS/NiTe/Ni positive electrode for supercapacitor, and the assembled asymmetric supercapacitor using the positive electrode demonstrates a sup...
