Abstract: The present application provides a nickel oxyhydroxide/carbon nanotube composite for a water-based magnesium ion positive electrode material, and a preparation method and use thereof. 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.

Abstract: The present invention discloses a lithium battery positive electrode material precursor and its preparation method and application. The positive electrode material precursor has the chemical formula Ni x Co y M z T p (OH) q , the positive electrode material precursor contains secondary particles in the form of microspheres formed by agglomeration of primary particles, and the microspheres have a three-layer structure from the inside to the outside, namely an inner core layer, a middle layer and an outermost layer. The ratio of the intensity of the (110) and (102) crystal planes diffraction peaks expressed as peak height in the XRD diffraction pattern of the inner core layer of the microsphere is 1.0-8.0. The positive electrode material prepared by using the positive electrode material precursor has high discharge specific capacity and good cycle stability, and can be used in high-performance lithium batteries.
