Enhancing the Stability of LiNi_0.5Mn_1.5O₄ by Coating with LiNbO₃ Solid-State Electrolyte: Novel Chemically Activated Coating Process versus Sol-Gel Method.

ABSTRACT: LiNbO₃-coated LiNi_0.5Mn_1.5O₄ spinel was fabricated by two methods: using hydrogen-peroxide as activating agent and sol-gel method. The structure of the obtained cathode materials was investigated using a scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and the electrochemical properties of the prepared cathodes were probed by charge-discharge studies. The morphology of the coating material on the surface and the degree of coverage of the coated particles were investigated by SEM, which showed that the surface of LiNi_0.5Mn_1.5O₄ particles is uniformly encapsulated by lithium innovate coating. The influence of the LiNbO₃ coating layer on the spinel's prop
