Abstract
- The cathode material Li<subscript>1.5</subscript>Ni<subscript>0.25</subscript>Mn<subscript>0.75</subscript>O<subscript>2.5</subscript> was synthesized through a solid-state reaction. In-situ high energy X-ray diffraction, STEM and electrochemical characterizations confirmed the composite nature of the material. We mainly found that the layered components belonging to the R...m and C2/m like-phases formed stepwise following the thermal decomposition and reaction of Li<subscript>2</subscript>CO<subscript>3</subscript>. Solid diffusion at high-temperature with extended calcination times cannot change the composite nature. [ABSTRACT FROM AUTHOR]
