A Novel Hierarchical Porous 3D Structured Vanadium Nitride

Most electrode materials consist of metal oxides and conducting polymers such as iron oxide [13], manganese oxide [20, 21], vanadium nitride [22, 23], tungsten nitride [24], and polyaniline [25]. To increase the energy storage and stability of the two-electrode materials, it is necessary to combine carbon-based materials with high-capacitance pseudocapacitive materials [6, 16, 20, 21, 22, 23].
