Abstract: A nickel oxyhydroxide/carbon nanotube composite for a water-based magnesium ion positive electrode material, and a preparation method and use thereof are provided. In this approach, carbon nanotubes serve as substrates onto which nickel oxyhydroxide particles are grown via a chemical bath method, yielding the desired composite. By employing this technique, nickel oxyhydroxide nanoparticles are synthesized directly on the surface of carbon nanotubes through a simple chemical bath process, resulting in the formation of a composite structure. This composite material, utilized as a cathode electrode in water-based magnesium ion batteries, exhibits outstanding electrochemical performance, particularly in terms of cycling stability and magnesium ion storage capacity.
