Abstract

The cathode material Li_1.5Ni_0.25Mn _0.75O_2.5 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 R3m and C2/m like-phases formed stepwise following the thermal decomposition and reaction of Li ₂CO₃. Solid diffusion at high-temperature with extended calcination times cannot change the composite nature. © 2013 The Electrochemical Society.
