Raspberry-like Ni/NiO/CoO/Mn3O4 layered heterostructure for supercapacitor and preparation method thereof

摘要: The invention provides a raspberry-like Ni/NiO/CoO/Mn3O4 layered heterostructure for high-performance supercapacitor and preparation method thereof. A simple one-step hydrothermal is used,HTM used as reactant CTAB guiding agent so that the material self-assembled to form with Mn3O4 inner layer structure NiO CoO particles outer structure, elemental Ni adhered surface of final material, wherein molar ratio Mn3O4, NiO, 1: 5: 3: 1. easy implement without complex or expensive reaction device, prepared uniformly distributed has no heterogeneous phase higher electrochemical performance production cost reduced composite expanded.
