Effect of synthesis temperature on the structural defects of integrated spinel-layered Li 1.2 Mn 0.75 Ni 0.25 O 2+δ : a strategy to develop high-capacity cathode materials for Li-ion batteries

An integrated layered-spinel of (1 − x )Li 1.2 Mn 0.6 Ni 0.2 O 2 · x LiMn 1.5 Ni 0.5 O 4 (0.15 < x < 0.3) was synthesized by a hydrothermal reaction followed by firing at different temperatures.
