NiO/Fe2VO4-based nanocomposite electrode
12469843 · 2025-11-11 · ·

A nanocomposite electrode including a substrate, a binding compound, a conductive additive, and NiO/Fe.sub.2VO.sub.4 nanoparticles. The NiO/Fe.sub.2VO.sub.4 nanoparticles have a substantially spherical shape. A mixture of the binding compound, the conductive additive and the NiO/Fe.sub.2VO.sub.4 nanoparticles, is at least partially coated on a first surface of the substrate. A method of making the NiO/Fe.sub.2VO.sub.4 nanoparticles is described.
