Electrochemical studies on cathode blends of LiMn2O4 and Li[Li1/15Ni1/5Co2/5Mn1/3O2]

Composite cathodes were prepared by blending LiMn2O4 spinel and Li[Li1/15Ni1/5Co2/5Mn1/3O2] layer by simple mixing/ball milling followed by calcination at 800 °C. The prepared blend materials were subjected to XRD and charge–discharge studies. The cycling results revealed that the discharge capacity and cycleability of LiMn2O4 can be considerably increased upon blending the material with layered Li[Li1/15Ni1/5Co2/5Mn1/3O2].
